This was A really fun game! Variety in enemies and the fact that the powerups made the next level feel harder was a great idea, I would buy everything though every round and at one point I couldn't buy anymore due to not being able to go over 5x speed, that was a bit of a bummer, I wish that it would have let me choose like hardcore mode and the enemies would have started to make like 2x the damage, but I could buy as much as I wanted :D 

I think the game bugged out two times. First time I went through the classic mode, beat the boss and then it started coming with normal levels again for few rounds before it through me back to start (I couldn't read what it said since it went so fast) Then I went to play the boss mode (again the 5x speed limit bummed me out a bit :/ ) and after multiple bosses I was left alone jumping in the level, with no way out and no enemies or anything anymore, had to ALT + F4 out from the game :D 

Overall amazing game even though it was so simply made.

This was so fun!! Really great enemy variety and progression, and the simple tradeoff premise was an excellent idea. At first I had trouble figuring out what was and wasn't hurting me, but that worked itself out. I'm not sure how it ended since it might have crashed me out and I couldnt see my hiscore, but i had such a fun time playing it. Getting to know the different enemies and changing up the priorities as they spawn was so engaging, really great gameplay. 

I really enjoyed this , Love the mechanic  and  soon got Crazy at the end level boss Well done great fun.

Really cool concept! I always love games that treat players' willingness to challenge themselves as a form of currency, and its executed really well here. Nice job!

I had a lot of fun with this game. The simple mechanics but hard gameplay makes this game really fun and kind of even addicting. This game was really fun!
