Hello,
A nice take on a retro shooter, the gameplay was really smooth, the music has a retro vibe which I like and a bit on the "heavier" side, the sound effects where okay, there was some clipping for the camera when moving to a new level, but that's a minor thing, I wish there were more levels but good job creating this alone in 10 days, I can see this being developed further, maybe add more weapons, like a grenade or something, I'm not sure :) well done!
