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.

Don't buy, it's no longer supported! This game won't run on one of my Windows systems and since they aren't even replying to requests for support I can't play it on my new system. It gives a Java out of memory exception even though I have plenty of RAM free, but since it's a Java app the -Xmx limits how much of your RAM it can use and while there are Linux and Mac shell scripts to start up the game in the Steam\steamapps\common\BossConstructor folder that you can modify to increase the -Xmx there isn't a windows batch file and I've tried adding a -Xmx to Steam's launch options but it doesn't work.
It's like a combination of Captain Forever, FTL, and Star Control. Music is pretty nice. Controls are a little skittish. Ship editor does not save the parts you take off of the starter ships, so they just disappear. You cannot reset this back to defaults. Just gone. The tutorial is very very limited. The AI can fly straight, but human ships drift in whatever direction you turned last. I wish reviews could be more than a binary thumbs up or down, but for a binary review, I have to call it a thumbs down. Really, I'd put it around 50%.

Still feels like an early access game with the bugs and lack of polish. Plus the overall game feel is just kinda scuffed and unfun. If you want good 2D spaceship builders I suggest Reassembly (a cheap but very fun game on steam) and Cosmoteer, (a currently free game in alpha where the crew inside the ship are simulated and integral to the mechanics).
This game is abandoned by the developer. The Java version is outdated resulting the game not starting up correctly, you can fix this by updating the version manually.
Great game. Can't say anything bad about it, except that it's lacking in content & weapons/modules for your ship. I wish it had more weapons/modules because it really doesn't have a lot of stuff and the different ship builds that you can do is rather limited. It would also have been great if the game used an open-world map, instead of multiple small sectors that you have to join/leave constantly. But like I said, it's great overall and well worth 15dollars. It's unfortunate that the game hasn't been updated in over 1500days since it certainly can still be improved and expanded upon... and the game is available in russia, which both are things that you'd just have to consider when thinking about supporting the dev or sailing the high seas instead.

Everything about this game is awkward: controls, UI, gameplay. Nothing is explained, user experience is at near zero. There's a tutorial, but it explains only some parts of the interface. You have to figure out the gameplay and the rules of the galaxy map yourself. Some blocks are very poorly explained. The worst thing is a completely brain dead AI. You just come into the system. Shoot at some number of repetitive stumbling around, but mostly not doing anything, ships. Do some awkward tasks (like "collecting the ore f. ast." whatever the hell it means. Why is there even ore, what does it do?
I am going to recommend the game because it can be fun and addictive. However, there is one recurring situation which completely destroys the immersion for me. Many of the missions (in exploration mode) have you fighting your own clone - an exact copy of your ship. Now for me one of the most enjoyable aspects of the game is building the best ship I can, continually improving it and going out to (hopefully) trash the AI ships. If the AI is just going to copy my ship then what's the point? The AI will ALWAYS have at least one ship just as good as my best. Of course I will still be outnumbered so while I am trying to take on my clone I am surrounded and torn apart by numerous other AI ships. Very frustrating and it just seems like a lazy way to "challenge" the player. That being said, you don't have to play in Exploration mode if it becomes too frustrating. I've moved over to Skirmish mode and am still enjoying the game very much. And just because I suck at this doesn't mean you will. Get the game and go kill your clone ship!

Tough call. It's buggy, badly optimized and the missions are repetitive. But it's fun. Real fun. And you can tell the dev loves their game. So.. if you expect a flawlessly executed. perfectly balanced space game, skip it. But if you're in for a great sandbox experience and don't care about having to sometimes launch it 3 times until the menu loads correctly, go for it!
