Upwell

Rocket jumping schmoovement
Master rocket jumping in a trial by fire. Launch to a ledge, dive for a heart, stomp on an eyeball, and chain actions together to maintain momentum. Don't be reckless: every blast costs health.

Acrobatic boss battles
When bosses emerge from the well, raw explosive power won't save you. Juggle yourself through the air and learn their patterns to dodge attacks.

Chaotic physics
Floating eyeballs aren't just hazards to kill or avoid. Use them to keep moving, or as weapons to send flying.

Permadeath roguelike

Procedurally generated environments with items that change the way you move, heal and battle. Only your own skill and experience comes with when you die.
