Sonic 2 HD

i reported a few bugs in 4x rez. I got sent off the stage after pressing down on the left of the map. Sonic flipped himself upside and "fell up" to the top of the map. Then I did spindash on the platform thats moving from left to right, and when I hit the wall, he got shot into the top of the map again and I was d/cd.

wierd lol

The 4x one has an intended function where pressing the A button turns gravity upside down. It's a featured function in the Sonic 3 physics.

Anything relating to your avatar flipping upside down like that is probably you accidentally pressing the A key, or related to that in some way.
