(Bug Fixes) 1.1.1

Bug fixes for the new update:

1. Game trying to get gamepad input instead of keyboard and mouse for some players
2. Not being able to go past wave 126 in endless mode
3. Not beign able to upgrade an unit past level 50

There are more things that i will improve next, like balancing endless mode better, and also smaller bug fixes, but i prefered to release this update fixing more serious bugs first.

Thanks for playing!
