Let me start off by saying I've refreshed the game several times so that's not it. I've even tried opening it in a new browser window.
My game: https://flowlab.io/game/view/597803
First issue is that I've chosen the Run and Jump behavior bundle for the character, but it only allows it to move left, flip, and move right. It cannot jump. Furthermore, when it does try to move right or left it gets stopped after a few pixels.
Yet sometimes, I will refresh and then it can move freely left and right, but still cannot jump. Any ideas what's going on?
Second issue is that in the editor my monkey object has its hind legs flush with the blocks underneath it as intended, but when playing the game it hovers a pixel or two above the blocks.
