Blake's Adventure is a fun adventure game for one or two players. There are four worlds and sixteen different levels.
Yeah, sorry about that. It's supposed to knock you back, but if it hits you just right (or should I say wrong?). . . It's solid so that might be the issue. I'm not sure if I could fix it. Anyway, I'm glad you enjoyed the game!
I'm sure there must be a more elegant solution, but off the top of my head I would: maintain the "Solid" behaviour for the boulder but add a condition where if "is overlapping" with Blake then "set Platform vector Y to -300" (or the number you think is appropriate). That should fix it.
Or you could just make boulders disintegrate once they touch the ground.
