Hey you asked for in depth feedback on discord so here it goes. Note that:
1. My own submission is not perfect by any means
2. I don't generally play puzzle platformers, you may want to pay closer to attention to feedback from your actual target audience.
I spent way too long trying to get past the tutorial level and eventually just gave up. I am assuming you were supposed to freeze the falling blocks in mid air, but it is way too fast and difficult to time, you have no way to unfreeze and quickly refreeze time to adjust it, and your jump height is not enough.
The tutorial difficulty was too much for anywhere in the game, let alone for the tutorial.
Here's what I would improve if it was my game and I had infinite time to work on it, based on the tiny amount I was able to play.
1. First, add a skip level button. Every game jam puzzle game should have it regardless of how difficult the game is, and your submission is in extra special need of it.
2. Add gifs to the itch.io page, you have nice animations and pixel art looks significantly better in gifs than in screenshots.
3. I would slow down the idle animation for the robot, and move the body slightly less. Your game doesn't seem like a high adrenaline shooter, you want the animation to reflect the speed of the game.
4. Keybinds very unintuitive though I appreciate you showing them in game. I would use space or enter (or both) for moving dialogue forward, and add the ability to skip dialogue. I would use maybe space for slow time and Q / E for forward backward, or some combination of number keys. Whatever you use, make sure it is reachable by the left hand and left hand only, you should not demand for players to have both hands on the keyboard unless there is no way to make the mechanics work otherwise.
Sorry I wasn't able to make it further in but judging by the other comments I am not alone in finding the controls overly difficult and frustrating. Remember that as the developer you have played the game for hours and hours and if you try to make it challenging for yourself, you will make it very difficult for the average player. One rule of thumb is to make it quite a bit too easy for yourself, and then it will prove a satisfying challenge for the player. Also make sure to add a skip level button on game jam puzzle games.
