Gorgeous pixel art and environment. Unique setting. The wall-jumping mechanic doesn't work all that well, but once you get used to it it doesn't detract too much.

Unfortunately, as a Metroidvania, it's rather simplistic. It's essentially linear, each key item just unlocks the next area. I rarely got lost, nor felt particularly rewarded for exploring.

The combat was a mixed bag. I think the boss design and animations were excellent. Charge shot has a satisfying feel. However, fighting regular enemies tended to be annoying, especially when backtracking through old areas.
