Fun entry! Congrats on your very first game jam!
Even though simple, I really liked the graphics. The 3d environment side scroller was a nice change of pace from other submissions so far. The controls were also very responsive, great job!
At some point I got stuck however, I'm not sure if I missed anything or whether the game was bugged (I kept getting an element error popping up), but unfortunately I was unable to figure it out :(
Thanks for your submission and good luck in future jams!
