Overall I had a good time with this game. The storytelling was fun and engaging, I was always looking forward to the next story beat. I enjoyed the boss encounters and the exploration for the most part felt very fun (I think exploring the nooks and crannies of the snowy area up top was my favorite bit, it felt cool to kind of "escape" out of the facility''s upper bounds Super Mario Bros. style). The powers were definitely very interesting and diverse.
Generally I feel that my feedback for improvements has been shared by many people below.
The wall jump accidentally clinging to small platforms interrupting the flow through the game is unfortunate. I saw that you said there's probably no real way to fix it, so that's understandable.
The Shift Jet could be finicky at times, but I eventually got the hang of it and almost felt like I could zoom along at a good pace. Transitioning between rooms and having to move my mouse all the way to the other side of the screen to continue zooming along also interrupted the flow a bit, but that's just how the mechanic works.
I unlocked the teleport ability before the ability to move blocks, so I was pretty confused as to what it did and was worried that I had missed something during the text pop-up. I eventually got it sorted when I found the shift ability, but it was confusing for awhile.
Anyway, a very ambitious project and I'd say given its scope and the wide arrange of abilities on display, you knocked it out of the park. Great job!
