great
its a good game but it still feels a little lacking.
I never really figured out how i know what money i was going to make and the achievements didn't really do anything for me.
I think it would be cool if unlocking certain achievements gave you cool hats, particularly the special hats since buying them to me doesn't really feel all that special.
Its basically a survival game which i find is part of games that have story lines or campaigns so i feel like having a campaign or levels with certain goals or tricks (such as hitting only blue platforms for a level). Rewards for the levels of course would be nice but just a few ideas i had.
Great work all in all and it looks like you are starting on the next one or at least thinking about ideas so i hope it will be even better.
