FYI: I played the 1.0.1 patched version.
I really liked the art! The gradient on the ground and the sky in the outside area is lovely.
The combat was tough to get used to, and like HalfAlieno I got stuck after falling in that down in that staircase area. Traversing the gaps is challenging.
Action games can be tough to get the movement and tuning nailed down for a jam (I know my game is a bit clunky in parts), but this was a good effort! Nice job!
