The graphics were so nice in this game. The boss seemed to have way too much health - I just couldn't beat it. The minigun was my favourite. I don't know if it was the must powerful weapon, but it felt like it was.
Idk why but the character was always in the bottom right corner, which made playing a little harder. The player should have always been at the centre of the screen.
Other than that, this was a really cool game, good job!
