This is BEAUTIFUL MAN! The game is well made with clean movement and stable ground collusion with the side of some sexy indie game art, what really hits this game home is that. it feels like it was made on another program like unity, or unreal engine!
It separates itself from look like an average flash game. Similar to fancy pants.
Pat yourself on the back.
Its also good to know that the date doesn't matter if you want to upload a game still for the jam!
my only concerns are framerates, if possible you can make a settings mode where you can change how the gameplay looks.
but that stuff is optional. If you are gonna make updates, focus on gameplay instead.
