I love games where you upgrade after each iteration, so this was definitely a delight :) I'd say maybe the rocket was a bit toooo slow off the bat, so the game itself had a somewhat boring first minute or so, but once I got more speed the game became more enjoyable :) I think I would love to see some more upgrades introduced so that the player has more choices and maybe even levels of some sort. But I know you were limited on time, so for what it is, it looks great and is a great foundation for a future game! Great job :)
