I had fun playing the game. It took me a few tries to beat it but after I saw your comment on holding jump to wall jump I was able to get through the level and beat the game. I enjoyed the ending, it made going through the game worth it.
There was a couple of points near the beginning where the game would freeze momentarily but then it unfreezes and you can keep playing. Felt like something was loading? Besides that the game play was smooth. Definitely felt like I was playing a metroidesque game.
The art was really cool, oh and the cutscene intro at the beginning was well made in my opinion.
Overall, it was a great experience with a decent challenge. I probably played it for about 30-40 minutes total throughout three playthroughs.
