A simple little puzzle plat former, starring a cute little forklift.
It's quite nice, especially for your first game. Difficulty scales nicely.
Make the "w" button jump as well and things can disappear if I push them to the far right if I'm not playing in full screen. Also, you can push the boxes a little too hard, I feel. For a puzzle platformer like this, you want players to feel they can very precisely control things, so keep physics to a minimum if you can.
Maybe add a button to throw the boxes though, so you can move things around a bit faster.
Overall a cool little game. Hope to see you in more games jams! :D
