This was pretty good. Made good use of theme. There were some design choices that were less than awesome for my own experience, but as the behavior was pretty consistent, I want to be clear that they don't seem to be flaws in execution, but they are things that hampered enjoyment.
Enjoyment: 3.5/5. I actually enjoyed this one a fair amount, but there were a lot of moments of what felt like cheap shots at least the first few times around, and some battle rooms that felt more frustrating that fun on balance.
Please in the future consider not making players face a wall to pull off a wall-jump. Probably a large portion of my frustration came from that.
Execution: 4/5. Very few if anything in the way of bugs. There was one puzzle that thankfully I was able to contact the dev about (thank you!) but without doing that I might not have gotten what I was doing wrong. Aside from that and a couple of places mechanical conveyance might have been better I think this was pretty well done. Also kudos for the time-pressure escape. Not only is it a classic
Sensory: 3.5/5. Pretty well put together and aesthetically consistent throughout. I wouldn't play it for the aesthetics, but they don't hurt the experience.
(Note: In my actual score, I'm rounding up on enjoyment and down on sensory since in my brain you probably have a better shot at winning the first category.)
Metroidvania: 5/5. Checks all the boxes, and kudos for basically making the dash and variations your centerpiece.
Theme 5/5: Good use of theme. Mechanically integrated. The story blurb on the page actually feels a bit like a distraction in comparison to the mechanical implementation.
Solid entry overall, a contender.
