Tip: Switch palace switches normally disappear if you replay the level. However, if you insert them as direct Map16 and use the hex-edit at $00EEB2 in the ROM map, you can replay the level without a problem.
This hack features much new ASM stuff. Never had a hack that much new objects (even though this hack is really small).
The mission - design was made through asm, so you don't have to collect the stars like "climb something and you've got a star", it's more like in the original
May just be my emulator, but the time limit for the "kill all enemies" mission is way too short. Also, crash problem (white screen) upon selecting a star for the Freezezy Peak level. I use N64oid, and i understand if it's unfixable for that emulator. My phone tends to lag with most of your asm. I know it's probably not your fault, but you know. Your hacks are incredibly unique, and well made. I just think you could do a bit better with level design.
