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/day in the week to Aug 24 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 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.

Reviews
reminds me of Genome Guardian 👍
Solitary Sentinel is an innovative rendition of space invaders that incorporates great fun, strategy and variation all into one. A must try for anyone seeking something novel and addictive!
Surprisingly fun, very good depth and replayeability. Game starts decently fast and gets extremely hectic in later waves in a fun way. The longer you play, the more perks there are to be unlocked. Auto-Aim perk can be utilised for a semi-idle game for when not fully focused. Lots of combos and synergies between weapons and upgrades and perks.

Fun game, has more depth and things to try than I was expecting. I do like how there's certain tradeoffs in the main gun. Play the demo if you want to give a quick try. Gameplay wise, would say it's good for a few afternoons but do feel like you probably have gone through everything in 5-10 hours max (unless you want to max out all the perks). A few issues I would point out just so people are aware (hopefully the dev will fix in the future). 1. Crashing. Not 100% sure why but the game crashes fairly frequently (once a hour or more) 2. Some of the upgrades can cause massive lag. The blackhole weapon seemed to be the worst for this when it gets big (and I have a pretty powerful computer). Recommend avoiding this weapon. Edit: Dev saw my feedback and issued a fix which so far seems to have fixed the performance (although now the issue is that the whole screen is taken up by the blackhole).Hope the people that enjoy these types of games can find this one which I think is underrated, just don't set your expectations too high, to me it is just a nice short chill game.
easy to learn, great and fun game even for newbies! really worth trying it out, and it gets more challenging & exciting as you play!
Worth a try with good ideas, welcome game in the Roguelike franchise
I enjoyed it but becomes cheesed with the lightning weapons. Also could use a speed adjuster as later levels take way longer.
