I like this one! Infinite runners were my first game projects too, they're simple and fun to make.
The hand drawn graphics are a nice touch, and the music selection fits the theme. There was attention paid to switching the music for the different states and it does add a lot to the vibe of the game.
My suggestion is to modify the speed of the player over time to make the difficulty ramp up as time progresses. Right now, it's a game with a flat difficulty curve, so players might find the experience redundant after they notice that nothing is changing in terms of their stress.
With a little tweaking, you can either increase the player speed, increase the obstacles, and while you're at it, increase the pitch of the music to add stress to the experience so the player feels the heat.
This was a cool entry! I'll try to snap some photos during the event
