HACK FEATURES:

🔹 Spin Dash: Sonic can do it by pressing Down + Button 1 / 2.

🔹 You can become Super Sonic from the start by pressing Button 1 (twice in a row). This was decided due to the short length of the game.

🔹 Free Jump: Button 2 is completely free for jumping (does not trigger the transformation).

🔹 Emerald Boost: By collecting all 6 Chaos Emeralds, Super Sonic gets a boost with multiple jumps and speed (like Hyper Sonic in Sonic 3 & Knuckles). The emeralds also help get the Good Ending.

🔹 Level Select: On the title screen, press Up + Down + Button 1 to open the level select menu with Player 1's controller (in the original game, you needed Controller 2).

I still lacked some animations for Super Sonic, but I hope to be able to add them at any time
