If this game doesn't win the graphics category there's gonna be riots, daaaamn the art is good, probably the best we've seen so far!!! It's so appealing, so clean, so smooth it wouldn't surprise us to see it in a finished product!
The game itself is more of an experience than an actual game, but that's completely fine! Specially for something made in a week, truly a great, great job, it's clear that a lot of love went into this project. Congratulations!
