I did submit the game well before time was up, but that was simply to make sure it was submitted in time as there are sometimes issues at the last minute due to the load on the site. I was still able to, and did update the game as much as I could 'till the deadline was up (I didn't take off from my day job, so I didn't have a lot of time on Monday and especially Tuesday).
Your assessment about death being bound to the spacebar is correct. I originally was going to allow for a jump, but realized it didn't really have any point. Then when I needed to test the death mechanic, I bound it to the jump button and just totally forgot I did that until it was too late.
I appreciate your feedback. I am considering continuing to update the game, though it would probably be in a new project as I want to keep this one, and all its flaws, for the sake of documenting my history and progress.
Thank you so much for playing!
