It's a bad sign
That the game only becomes good when it glitches. I can't deny the graphics or sound as being good, but the game it just brutally hard and unfair. Somehow, through some sweet mercy, my game glitched on the first level and my gun was suddenly doing 100 damage a hit. Suddenly, the game was fun, because it was possible to win. Of course, that still didn't change the fact that the first level was total BS. Rooms with green slimes, laser shooting slimes, 3 magnet things the purple blobs that block your screen and the wall mounted lasers. It's not fair, and if my game hadn't glitched, I know it could never have gotten to stage 2.
Oh, and let's talk boss. It had something like 5k HP, 3 magnets and constantly moved around and damaged you. Not fair and you know it. The game is quality, but is absolutly positivly no fun at all.
