Another duck on wheels amazing submission! Really impressed how you took the boss level in a race game and actually made it fair. Stomping on the rat at the start gave me a boost and then trying to get the upper pathways. Tried to play it on stream but it lagged.

Now, it took me 6 rounds at least until I've managed to win. Great work on having the rat also fade to the background and being invulnerable. Checkpoints were appreciated in all the previous rounds, this one included. Congratulations!
