Slendytubbies 3 survival 4.0 mod

i just wanna say that the game is buggy and here is 2 reasons for that.

1: the game has invisible buttons which nobody could see. making it impossible for player to start the game.

2: the game crashed on wave 2. everything was fine until the wave 2 started my game crashed for absolute no reason my pc was good though.

so please fix these bugs. the game could be beatable without crashes.
