Found a bug: Make much money in one game -> Buy upgrades -> Start new game -> Exit the game to the menu ("||" button in down left corner) -> You have money from your last game -> + so dev can see it
Make it so that unlocking new weapon will not take weeks. I mean, unlock mine:kill 10k baddies with barrel ... realy, 10k? make it like kill 1000 baddies with barrel, or use barrel 500 times. + if you agree
