Found two crashes, but this is amazing
Hell that was one charming first level.
I've been waiting for this since I've seen a screenshot I-don't-know-how-many-years-ago featuring this Isometric-styled perspective reminding me of the fun I had playing SEGASonic on the Mame Emulator.
This got to be one of the best mods ever happened to Srb2. The graphics are beautiful, the music catchy and, good Lord, bosses that are not the basic Eggmobile and are actually fun to play.
However, I found two major crashes. I don't know if anybody posted these already, but, navigating through the comments, I don't remember seeing them. Not forgetting this is a beta, but you might want to fix these.
1) Game crashes trying to spawn a player in Match Mode
This one is pretty obvious. The game forces TDHub to load as a map and it simply has no spawn points nor ways it could be used as Match Mode. Don't know if, due to the exe being edited from the vanilla Srb2, it can't be temporarily disabled, but I would suggest that.
2) Game crashes quitting a stage during Record Mode by "Abort"ing it
I just entered Checkered Mountain again by accident, tried to quit, and the exe killed itself. I tried again on another stage, and the exe killed itself. Whelp. Unluckily, I don't have the error log right now, but, if needed, I will try to replicate the crash.
Still, 10/10 would play again. :)
Ps: IMO the main menu theme song becomes annoying after 3/4 times. I don't think you'd have it changed, but compared to the acts' catchy tunes, meh.
...Do the boss stages need to be act 3?
