Nice game! I had a lot of fun playing and it looks really nice overall. I'm not sure if it was compression or the import settings, but some of the sprites looked pretty pixel-ey for the overall theme. The gameplay was nice, but I found that weapons usually fell too quickly in my opinion, not sure if they were supposed to be hard to get. I liked the transition between stages and the bgm was also good. The particles and small details, like enemies falling into the drill, were also great touches. Good work!
