After you reviewed my game, I came here to play yours, and I'm glad I did!
Enjoyment - 4 Stars
This game was fun! My only complaint is that the boost seems a tad underwhelming for how much fuel it uses, and the tire bounce is quite small. I think this game could benefit from a controlled jump.
Creativity & Theme - 5 Stars
I love this! The creativity is definitely there, a flaming tire rolling down an endless hill.
Visuals - 3 Stars
Flat colors, rim shading only, and color gradients aren't good graphics. I will give you a point for the flaming tire though, as that's a hilarious addition XD
Audio - 5 Stars
You have pitch shifting, which is extremely important for repetitive sounds. The music also fits with the game, and I like that!
Seriousness - 5 Stars
A tire rolling endlessly with the goal of never stopping is quite serious.
Great game, thanks for making it!
