Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0.43/day in the week to Aug 17 → 0.14/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

It's good! There are multiple endings and I'm satisfied with my playthrough. I use a guide often when I game, but without one this game might get a little tricky. I'd give this game an 8/10. I'm a huge horror game fan and I like the atmosphere, settings, and aesthetic of this game. My record says about 7 hours but the game recorded 3 and a half for me. I liked this game for its artistry, plot, and haunting vibe. The combat is okay, but this game isn't very scary. I was initially let down by the lack of horror and terror, but the artistry and story brought me back. If you're looking for an introspective, touching, and haunting art piece, this game isn't too bad, but honestly, the lack of horror might make it a hard sale. Thanks for reading and wishlist it if you want cuz honestly it's a pretty good game! :)
Good game if you like Resident Evil

Pretty cool survival horror game, more about exploration and puzzles, there's few combat and it's not the main point. Immaculate vibes and very nice backdrops (prerendered or not) If you miss old school Silent Hill and look for horror games that are, in a way, comforting, this one is perfect
The game relies heavily on nostalgia, and my God, it works really well. If you play it which I highly recommend you’ll be reminded of old PS1 games. The music is sublime; kudos to the composer. I put 25+ hours into this game and enjoyed every second. Hopefully, we’ll see more 8.5/10 games like this one from the developers. Thanks for the game :)
Lo-fi survival horror that stretches across several excellent ideas without ever overstaying its welcome in any particular area, centring a quickfire camera flash mechanic. There’s plenty of homage — play really feels like a combination of classic Silent Hill and Resident Evil in the best of ways — but each area brings new ideas to the table.
game looks good but unplayable due to a bug game will make you walk in a circle and there does not seem to be a fix for it out there even though many people have had the same issue
Heartworm is a good game, despite a number of shortcomings. Its story starts very strong, very intriguing and personal, but unfortunately starts to lose some momentum halfway through. Narratively, Heartworm is ambiguous by design, evidently... but even with its auteur-flavored style, it doesn't end up being memorable. Visuals are nice. Landscapes are imaginative and even awe inspiring a couple of times, although some of them are too in-your-face tributes to older games. Something I found amazing is how places in Heartworm look like pre-rendered backgrounds, BUT are actually 3D! It's genuinely impressive the first time you notice it when aiming over the shoulder or when the game decides to move the camera to follow you. I also loved all the real-time cutscenes... but absolutely disliked the pre-rendered ones, which obliterate the game's looks. :-S The ending videos, I.E. And talking about art direction: it's kind of all over the place. Suffice to say that Sam (MC) has very different looks and faces wherever she appears: artwork, in-game, status screen, the aforementioned ending videos, etc... The user interface could've used more work, too. And the in-game map is "functional", but an icon showing where Sam is and where she's facing was truly missing, for me. PC optimization is decent, but I think it could've been better, especially in scenes with many light sources, heavy effects and/or vegetation. In terms of sound and music, Heartworm is solid. Not a lot to say about that. Maybe voice acting leans towards the weaker side sometimes, but nothing too distracting. Gameplay wise, Heartworm is just fine. It DOES feel like a survival horror game, on the "gentler" side of the spectrum. There's almost no enemy variety, but this is understandable, as this is not a combat-focused game. There are a number of bosses that feel challenging and fun to beat, though. Controls are OK, but there's a problem after aiming over the shoulder: the camera will have a slow animation to go back to its default position and this can be really annoying in combat, where every second matters. This issue alone made me go back to the retro aiming mode more times than desired. Replay value is kind of there, if you're interested in getting all the endings and unlocking some costumes for Sam. For me, though, I didn't care a lot and felt I was done with the experience after my first playthrough. So, all that said, I think this game is worth a try, especially for survival horror and retro fans. Just keep your expectations in place and maybe get it on sale. From 1 to 10, I'd give Heartworm a 7.
I think if you like the original Resident Evil and Silent Hill from the 90s you will enjoy this game.
This game at every turn ruined any enjoyment I could of had here. Far too many enemies stun you and the dogs are so frustrating to fight or escape and for some reason you included them within a boss fight which simply did not need it. And in that boss fight after it does the stunning roar sometimes it just ran me over as it escape and ALSO the leap it does at you WHAT I AM SUPPOSED TO EVEN DO???? The dogs slow you down, ambush you, constantly stun you so that is then punished by the deer leaping. Also stop putting healing items in places were you risk losing health to get them, entirely defeats the purpose
Very good game! The story, the atmosphere, the level design, the music are all phenomenal. The actual gameplay and combat are the weakest points of Heartworm, and I won't say that it's *bad* -- just weaker. None of the puzzles are too impossible to figure out on your own, although a couple are presented a little vague and you'll need to stretch your imagination a bit farther to come up with the answers. They do provide the satisfying "aha" feeling of solving puzzles, though, and as a retro throwback to the games of the PSX-era, it even feels appropriate. The combat is, I'll just say it, kind of lame. I love the idea of using the camera as your weapon, and having film as the ammo. Super cool idea! But the enemies just aren't hard to fight, and partway through the game I nearly stopped registering them any more than minor environmental hazards to avoid. So it isn't a hard game, and there isn't a lot of enemy variety. That disappointed me. Regardless, I would recommend this game. Heartworm isn't the kind of game that will make you afraid to play with the lights off, or leave you with existential dread when you're trying to fall asleep that night, but you will have fun playing it!
