Interesting take on the Greek myth of Sisyphus!
The music and art are nice on their own, but together I feel like they got across the wrong kind of atmosphere. The art says Castlevania, darkness, underworld. While the music says arcade fun.
The core mechanic was nice too, though the player gravity is wayyyy too low. There was sections where I was flying in their air for easily 10 seconds, just trying to push the boulder.
Not a bad entry at all, was a fun, engaging few minutes. Getting the boulder over the ramp was VERY satisfying.
