The sound design fit the retro style graphics perfectly! The sound of shooting was really satisfying, and I loved getting the automatic weapon so I could just rapid-fire at everything! I won't mention the aiming thing, since I see that other comments posted about it, but I was definitely struggling on the first section! I would suggest adding in health packs in the beginning to help ease the player into the game, as I found I would almost finish the level before dying because I was low. Other than that though, the mix of 2D sprites and 3D environments was very cool, and I liked how you could choose between two weapons before you hopped into a level! Good work!
