Brony Blaster - A new game for the NES

My main project these days is a game called "Brony Blaster"
As the name might suggest, it's a game where you blast bronies and My Little Pony characters. Currently, I am making the platforming engine and fixing many glitches, but when this is done it's just going to be a matter of Level design.
You can download a WIP ROM to play on an NES emulator at the link below, but it's an old version that has a few glitches (Such as ladder climbing, which is broken).
At least you can blast a few ponies in this version Tongue
