I'm just finishing a few fixes to Demo ZX before starting the recompile of Demo SP, but I nerfed Super Bombs on Level 3's boss because essentially, you could one-shot the boss's second form in Demo SP and before. This is cheap and needed to be fixed (don't worry, you can still two-shot it and it's still easy)
As instructed in the comment, a new update has been posted so people can get past the Gohma now. Just didn't want to make 50 million pings.
