Alt+F4 did nothing, I couldn't switch to another window since I was in full screen, I had to ctrl+alt+del and sign out of my Win10 user profile and then sign back in. The stage was funny at first but then I died and my PC softlocked because I was just stuck in the dying state at the bottom of the screen and couldn't respawn. My experience here is the ONLY reason I gave you one star. Then I got to Lost Valley and perfectly understood why you use such Forces style stage layouts. Stardust Speedway isn't even worth mentioning since it's just a bunch of platforms placed at random and then Death Egg Zone recycled.
Then I did the exact same thing in act 2. It was cool in Palmtree Panic 1 when I got the invincibility and then blasted through a ton of enemies. Your stage design is very Forces-Classic-Sonic-y, in that you've got a lot of very simple platforming with 'hold right to win' type gameplay.
