Great game!
I really enjoyed playing this! I was feeling like a boss for the first two levels whooping ass as I went along with like 6 lives and some like level 6 guns (with missiles) and then the second I started the third level, I died. SO IT WAS OOOOON!
Great fun to play anyway, I love the pixel art style and I really liked the level up system as well, really nice touch.
Keep it up man!
