lots of glitches with controls if popping pills while approaching door you're frozen without a weapon. also sometimes after that if i hit q to change weapon i do the pills animation and come back to the same gun, but i still have pills to use and no health healed.
why dont noobs understand that the game is free the pay levels are just extra content. you still get 8 levels you can play in 5 different modes each. and the items just make the game easier for those willing to pay.
