I'm a real sucker for metroidvania style games, so that was a bonus! I really enjoyed the story and the way it was told. Definitely reminded me of some of the indie darlings that have grown really successful! Keep making games, I definitely expect to see great things from you!
The final boss was pretty tough, and I had to work out a strategy to actually win. The upgrades were fun and worked well and exploration was exciting and not tedious. I appreciated all the small details in the map.
I do have to say though the distortion effect almost made me quit playing. It was nauseating. For such a strong effect it'd be nice to include an option to turn it off even if it sacrifices some of the aesthetic.
