cool game
===============
some things to fix:
- rounding problems on some effect % values (59.999999%)
- getting both armor piercing upgrades gives the enemies armor back (?)
- sometimes enemies ignored the freeze effect and kept moving at normal speed with the frozen sprite
===============
other suggestions:
- add an upgrade autobuyer so people don't have to leave the game running with an autoclicker
- maybe add an option to disable damage text? should help a bit with lategame performance
