Hi, thanks for playing!
I realized there was an issue with the jump sound, and that was the best I could do at that moment... it was actually much worse before it was fixed to that point.
I will consider a one-way platform, but as of now, my intention was to only let players access those vertical platforms strictly by jumping off the sides. I will experiment with it, and try to create a stage with those one-way platforms to see how it goes.
