Really exciting game you've put together here! This game is chock full of nice touches that make it feel great: sweet sounds, graphics and effects all work together to deliver explosive action. However, while it is presented very well, the gameplay design does kind of work against itself at times. For example, while the collapsible floors are neat, they ultimately make the gameplay a bit frustrating to climb back up and reach the aerial enemies. Speaking of the aerial enemies, it can also stink to get stuck with a certain weapon that doesn't work for your situation, like a sword. There are also some dead patches of no action or repetitive waves at times. Also the elevators should probably take you to the opposite side so there is no confusion on what direction button to press after entering/exiting. I hope I'm not sounding too harsh or anything: I definitely had a bunch of fun with the game and want to see more from you as you've clearly got a knack for cool stuff!
