This game is a pretty awesome one, keep up the good work. The gameplay is fast, dynamic, and Sonic feels really great to control. Graphics are unique with an interesting design, and backgrounds are just amazing and have a really good depth. Names of the zones are pretty interesting as they feature equal first letters of each word in them (like in Sonic CD), which is a nice touch. However, I want to note some moments in this game that aren't great:
- Wind Shield. It's too op. Not only it's a literal insta shield with a bigger hitbox and lifetime, but also can attract rings and even do a hover. It would be pretty nice to see some changes to this shield, like it should be either a better insta-shield (not op one) or more focused on hovering.
- Billboard at the end of the stages looks little bit off as it looks like it was taken from the Sonic Mania, and it's unfitting as the game prefers colours that have some twist in them, and it's not very pleasing to see some vibrant base colours out of nowhere. (Edit: it also has a wrong Sonic)
- Sometimes, in Relic Retreat, you can see some floating lava next to the quarter loop (either in act 1 or 2) but it's not a critical graphic bug. Edit: it's actually in the 3rd act
- There are too little levels lol
Nevertheless, good luck and take your time!
