Sonic Mania, but it is Scratch version | Sonic Frenzy 1 & 2

Sonic Frenzy is fun fan game that seem like Scratch (nor online) version of Sonic Mania. Sonic Frenzy 2 is a lot better than 1st one in my opinion for adding extra things. Sonic Frenzy: https://scratch.mit.edu/projects/172568408/ Sonic Frenzy 2: https://scratch.mit.edu/projects/712238482/
