If you jump onto a block and the square is bouncing, then just hold the down key, and when you stop, it will stop bouncing. Arrow keys to move.
Should i turn the spikes into the Neverseen? But why would you jump over the Neverseen......... Maybe after the end i can add more like where Silveny and Sophie land? in a forest? Comment if you think i should add more and what you think i should add.
