No tower skins sadly, the main cause of the loading time is the number of assets, adding costumes would just explode that asset count which I'd rather not do.
Yeah you're right mastery mode is very hard sorry! I'll try fixing the rbe issue thanks.
I understand, thank you! Also when I download the sb3 and run it after packaging it most tower sprites are very big and using bomb shooter causes decorations on the map when I run the game after packaging the sb3 to disappear and reappear.
Ah yes unfortunately that is due to certain limitations on scratch, I recommend opening the file using turbowarp offline editor (that’s what I’ve used to actually code this) and enable Remove Fencing and High Quality Pen in the advanced settings.
I’ve also implemented a fix for the mastery rbe in the browser version unfortunately I have to go to uni today so didn’t have time to update the downloadable versions, will do so in a few hours time when I get back home.
