Robbie Fraser Awesome game!!!!!! Gj guys, really, I finish the game like 5-6 times already. Plsssssssssssss add the free mode, with unlimited waves(you can use simple logic, for example - aliens will appear every 5 minutes, first wave will be - 30 tier1, 5 tier2, 2 tier3, 0 tier4, and then every 5 mins +10%).
