It was intereting to try to find the right combination of movements to go trhough a level
I didn't thought there was a wall jump at the beggining, fiding it made it pretty fun to go back to the levels
I don't know if it was because of the screen settings, but I wasn't able to see the whole level before buying things, if it's the case it's making it a bit more tidious to have to go through the level one time to see what you need
Nethertheless, good job for your first game !
