No instructions about the inventory meant a lot of fumbling before I finally pressed E. Not sure why E should signify inventory, but alright. :)
Some of the puzzles were interesting, but your decision to not have checkpoints kills this game. Making a mistake later, costs you having to replay everything. Which, for bonus, replays all of the audio. Out of sequence. No bueno.
When I got to the Simon says bit, I thought you would stick to the theme an make me chose a incorrectly deliberately. That didn't seem to work, so I tried following the sequence. By pure chance, my sequence never selected the top left block. After about 8 elements in the sequence (I may remember incorrectly), I started thinking. C'mon, has to be the top left, the game is a lie. So I pressed it. Whoops. Sequence reset. At which point, I proceeded to quit. The simon says puzzle was boring. I wasn't going to do it again.
Graphics are inconsistent. For the majority of the assets you use plain colour, whereas the main character has a blurry png, the inventory items have sharp pixel art instead. Also, some of the floors are these checkered white and black tiles, which is uncomfortable to look at when you traverse them.
Audio: there's no music. The voiceover is OK, but it's boring to have to listen to it over and over.
Performance. The red path that's longer than the blue one, has an very significant frame rate drop when you go south.
Camera. Why is it off center? When I walk West or South I can barely see ahead of myself.
In conclusion, not a great entry, from my perspective.
