The games isn't finished but is playable (not fun to play with, sadly).

Left/right arrows to move
Up/Space to jump

Pick the Golden Gem at the far right of the level
Each time you pick the gem the assets resolution drops to half

Every level is different from the previous one (procedurally generated from multiple templates)

The game don't have an end, you need to refresh to play again.
The game have some problems with collision, so you need to "shake" if you get stuck (jumping solves the problem).
