Damn amazing game, great feel while it's simple.
Few notes:
1. Brad did a great job on the music, his name Immersion fits haha :)
2. I think the words 'damage' and 'firerate' are kinda swapped. When I upgrade damage I get more firerate and vice versa.
Anyway awesome! Already curious for your next game dude!
My rank is Alien Master I won!! This game really gives a great sense of achievement, it's not that good in terms of graphics but is a really nice first game!
thanks
