I really love the concept and it has a clever gameplay mechanic.
It's almost an anti-platformer in the sense that unlike Mario or Sonic which encourage fast gameplay, here it's patience and diligence; not rushing through the level at breakneck speed that reaps the best rewards. Very refreshing in a way.
Just needed a few more traps, variations and a bit more detail in the level design and this would be top tier for me.
Nonetheless, a super cool browser game which I hope you expand upon post jam. It's really got all the bells and whistles already it just needs more of them.
