Done all the levels two or three times. Game looks quite nice :) Player movement can use some polish, IMO it's too unresponsive: faster acceleration would make it much better in my opinion. There are some occasional bugs, like you can shoot yourself into the air by holding jump when touching an legde's edge with capsule's side - but it's game jam, whatever :) I really liked level design, each puzzle works differently and provide different challenge. Overall, simple but still fun, good job! :)
