Game is just way too big, unplayable in less than 1080p, which leaves a lot of people out. Also, no real reason to play it, just shooting until you lose and get a score? what's the point? too simple.
Last boss too easy, you get 10 times the money you can actually spend, which makes it boring. This needs harder boss fights, more upgrades or ugrade levels/ships, so you can actually do something with the money.
Don't take it in a bad way but this looks just like a Idle Mine rip off, with a lot less upgrades, different drawings, but exactly the same basic system to work
About the "hold space to speed up", not important, I just put my cellphone on it and that's it. But I find it quite slow even in a dual core with 2gb ram, and way too much recycled stuff make it look more like a level pack.
You know what this game needs? an easy way to close all menues and windows, like clicking outside their area, so you can easily close more than one at the time
It would be cool if this game wasn't so unstable, but frankly after two times seeing it getting stuck and having to start all over, I'm done with it, unity is such a cr***y player, they are way too heavy for the system even for games with no real graphics, like this one :/
