Very cool take on this type of game where instead of having to parkour up a pre determined level, you create the level yourself by playing the game. I found it very satisfying to place the platforms and line up jumps. Great work! You should definitely expand on this, more platform types would be awesome. Maybe one that is bouncy, or one that you can place while falling like a safety net. Collecting different platforms types of platforms while playing (maybe good ones are harder to get to or off to the side) could introduce different gameplay scenarios for players. They'll have to decide to either keep climbing or take a risk to get a good platform that can launch them or something
