I'm super impressed with everything about this game. The unique movement, the graphics, the weapon variations, it's all extremely fun and great! It did take me a bit to get a hang of moving the centipede around, but I had a blast. I even ended up playing the game twice to explore rooms I hadn't gone in yet.
Though, I think that there could be less weapons? Or maybe a bit more balance of the damage output? After going to the central room, picking up the machine gun, and then going to the north most room and picking up all the guns there, the game becomes a breeze to get through. I didn't even need the laser weapon that can be found later on to beat the final boss. This didn't detract from my experience but I thought you might want some feedback. All in all, a great game, good job!
