Amazing game, the idea of the word CHAOS is pure genius. Everything works perfectly, i'm no fan of the pixel art but that's just me. The upgrade mechanic is really good also and it helps a lot.
I'm a fiend for incremental games, so I was trying to capture a bit of that exponential progression feel from those types of games. It worked with the coins and the altitude upgrades, but those are a little slow to get to. I hope you enjoyed yourself!
