Pretty excellent, except that the upgrades are a little too potent. Especially the very last one bullet upgrade. Didn't get it on my first playthrough, but when i tried it later, those things just annihilated even the final boss in moments, which is kind of silly.
Reviews for "Boss Slayer"
awesome game with great music, no challenge once you are fully upgraded though
Awesome!!!
It was decently done and worthy of like 10-15 minutes of entertainment. The music could use some work, however.
Kick ass! That was fun!
