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): 0.14/day in the week to Aug 23 → 0.29/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.

This game was a lot of fun! It's very simple and straightforward but it makes it a nice casual shooter. I love how the music and the visuals mesh together. It makes this satisfying sci-fi feel that's also nostalgic. It reminds me a bit of Galaga but circular based. The game play is basically just seeing how long you can survive but if you leave the bounds of the map you take damage. I only managed to unlock 3 ships and an engine, but there's probably a lot still left for me to see. It really does feel like an arcade game. There's a little slot roller for whenever you unlock something new and the sound effects are such a nice touch. I definitely recommend trying out a bunch of different ships. They're each different in design but also for play style. It keeps the game interesting while adjusting to the player. You can also see it as a sort of challenge though, trying to get farther with each one.
Great game! I really enjoyed the gameplay and the overall experience. Well done!
