I can't believe you did it!!
Ever since the multiplayer update we've had so much fun! It run so much better in single player too. The power ups are awesome. I figured out the smoke was from where the bullets landed so I try to use those to find the remaining enemies. Enemies can only shoot at you when you're facing them which is neat since you can only turn around so fast.
At some point we went into edit mode and somehow froze all the enemies and were able to look at them up close and shoot them. Pressing select brought up the code which kind of acted like a map which was interesting. We had some classic fun with hide-and-seek, screen peeking, and betrayal <3
If you wanted to increase performance you could probably cut out the entrails and I'd personally be fine. Sometimes it's useful to see where an enemy just died but there's already a lot going onscreen.
A cartridge release I think would be great. I already want a full color manual with backstory on the enemy characters. Like who are the big bazooka guys? Or the pink slimes? Do they behave differently? Are they from Mars?
