I'd normally say "yes, this is fine", but 30 bucks is a steep ask for what it is, to be honest.
Let's get gameplay out of the way first:
It's a rogue-like/lite. Your character doesn't really gain any strength between runs, save from 1 bonus out of many you can unlock that influence the run. Other than that playing unlocks new items that can drop during runs. Some of them good, some of them not so much. You could argue that by increasing the item pool you'll actually make the game harder, since it's more difficult to build a certain way, but at least on easy and normal I didn't really have that much trouble.
Other than that you can unlock different characters. They all kind of look similar, because they're just "skins" for you to wear. And what you wear depends on the cosmetics you've unlocked, or rather, purchased, because this game has monetization, and that's another downside, to be honest. The various characters play suitabily different, but then again, not really enough. Playing as the Magma Miner isn't all that different to playing as the Godspear or whatever it's name is. Each has a different passive to build around, and some prefer status effects or damage reflection over other things, but ultimately you can build them the way you want. Their 3 distinct skills are often not that distinct, but variations of damage in a line, cone or area. It's fine, but nothing ground-breaking. The last unlockable character, the Star Captain, is locked behind an arduously long quest chain, which I have no inclination to complete.
2 more skills can be picked up during a run, but they're shared between all classes. Furthermore you can augment your run with items and skill upgrades. Combat is differentiated between getting hit in the face, which can only be avoided by killing the attacker or mitigating the attack with armor, which is rare, or having to move out of an aoe effect. This is where the unique movement and attack system comes into play. You can move freely around the arena ... in a circle depending on your movement speed. Position yourself wisely to avoid incoming damage. Sounds good on paper. In reality, especially in boss fights, you take UNAVOIDABLE damage, and that sucks, especially if you have a glass cannon build that suddenly gets oneshot without anything you can do. Lesson learned, I guess, but it's just a cheap way to stop the player from actually stacking these items if they can get them. Risk vs. reward is out of the window when the risk is guaranteed, and the reward cannot keep up.
That's the main hook of the game: repeat the content ad nauseam. Each run has you go through 2 different areas you won't realize the difference anymore after a while. They have their unique enemies, but they all kinda blend together after a while. Then you fight 2 bosses, 1 for each region, and a final boss. The game has you collect and visit various items and locations to progress its story. Said story is yawn-inducingly generic and boring. Something evil is going on and the Ink-guy wants to stop it, so in you go, over and over again. Then you return and you get to do it all over again. Now, do 5,000 damage to a specific boss. In you go. It's just there so you have something to do.
The story and characters are supposed to be cute and interesting, but I just found them annoying. All the modern tropes are there, of course, including the voice acting. Like I said, nothing is terribly bad or offensive. Everything is "fine", but nothing more, imho.
I'd get it during a sale, perhaps. Unlocking and testing out all characters will take around 10 hours or so. That's okay value in my book. The USP of this game is probably its co-op multiplayer, which likely requires friends, because I can't picture this with randoms...
