Aww if you had time to make more levels it would've been super cool, especially because you have so many gimmicks that probably took a lot of time to create AND animate (the vent specifically) but you just didn't use them to your full advantage.
Still, for the two-minute playtime, everything is very smooth, telegraphed, and polished, which is definitely something I don't see in games that don't already have like 50+ ratings by now (and also according to your description was what you were going for so good job). I especially appreciate the telegraphed stuff, with the red and yellow rectangles that just as easily could not exist and make the levels a lot more annoying.
Tell me if you add more levels after the jam if you're somehow not already sick of gamedevving for the past four days
