FUN! Incredible what you did in so little time! Colliders are on point, it's perfect the way the bad guys jump on the robot! Way to go, mate! I liked how responsive the sound was, although the blips become a little tiresome after a while. Very satisfying to catch a wave, I mean, the blue area that boosts you up? The turning animation was cool too, the robot's expression is altogether insane! I didn't care too much about the shooting part... Make it a vertical escape game in which catching the wave is primary goal, then it would maximize what I loved most about it!
Thanks for sharing., and please do continue making games (you mentioned in the page this is your first)!!
