Firstly, I made level design like this because I tried to make a "flow" that you can see in classic Sonic games. I think, that's what this looks like this for now. Secondly, I thought about making first act more "faster" than other acts: Act 1 - Fastest, Act 2 - Still fast, but with some platforming sections and more harder to walk through, Act 3 - Much more platforms than act 2. All in all, thank you very much for your criticism and your honestly feedback. I'll try to make act much better!
