Holy hell!! That's a whole load of precision platformer perfection! The controls are tight, the physics are just right; I felt great getting those cookies!
The lap system is a smart difficulty management decision, especially for a game jam, but it's also just really fun going through variations on the same good level.
The art's great, too. Goober is a charming goober. Despite being in the same palette, all the level elements are quite readable. The music's great, too!
My only concern is that the audio seems to be mixed a tad loud. It consistently peaks at, and sometimes above, +0.0 dB.
Fantastic! Great work!
