Hey congrats on submitting to your first game jam! It's always a lot harder than people realize and I'm sure you learned a lot.
That said, the jump mechanics weren't really working for me and I couldn't get over the first black column. Sometimes it would single jump, sometimes double, and sometime triple, but somehow never enough to get over that dreaded black column.
Anyways, congrats again on finishing your first (of many) game jams. Would appreciate if you checked out our game too. Best of luck!
