It's a fun platformer! I got to the test level and I tried out the high speed mechanic and it actually feels pretty satisfying to chain rolls and high jumps and dashing together. Though I wish you implemented it somehow in a puzzle, since it feels quite nice to do those mechanics! One nitpick on the controls is that the dashing sometimes doesn't register correctly. Trying to do shift + space at the same time in the air sometimes gets ignored and I lose momentum?
The artstyle is actually pretty good for the theme, it's quite simple but effective art. The premise of the game also fits well with how your gameplay loop is implemented! I thought the robot exploding and not being able to restart was intentional, I just restarted the tab and started from the first level again.
I think with more polishing both to the controls and some level designs (more levels if you have time!) then it'd be cool. Sometimes the levels are designed in a way where I don't even need to stomp on the robots since I can just do the high jump and get past an obstacle! Overall it's a fun platformer with promising movement tech
