and the spring it bounced on the very first one made shadow moonwalk and also took every physics the game had away

well here is the information!

Sonic Solaris is the (soon-to-be) ultimate tribute to the Sonic games of days gone by, brought to life by one overzealous fanboy! Combining the very best elements of both the Classic and Adventure era Sonic games, Sonic Solaris is aiming to be a totally unique 2D Sonic experience.

Sonic Solaris features four different playable characters, each with their own unique abilities! Traverse tricky terrain at high speeds and discover secret pathways with Sonic's elemental shields, Drop Dash and Insta-Shield! Decimate all who stand dare to stand in your way with Shadow's Homing Attack and powerful Chaos Blast! Preform awesome acrobatic martial arts with Knuckles' Flaming Uppercut and mighty Punch Dash, and just blow stuff up for no reason with Bean's arsenal of unstable explosives!

Currently featuring one SAGE exclusive level and a mini-boss, the completed version of Sonic Solaris will include seven full-length stages, eight bosses, a tutorial area, an expansive hub world, fully-animated sprite cutscenes and an extras menu with cheat codes and a sound test

Other features of the New Beginnings Demo include different invincibility themes and credits sequences for each character, two hidden Red Star Rings to collect, physics-based visual effects like homing Chaos Drives and scraps of destroyed Badniks that bounce on the ground, completely reworked sound effects, and a special secret hidden somewhere in the level. If you find it, take a screenshot and send it to me, and you'll get your name put into the credits of a future demo!

another side note when i found the bug and all the creator of the fangame(MangoLaCroix) gave me a comment and was glad i helped point out the bug and all i wonder if i will end up being in the special thanks of the full game who knows i was told by them they would send the game my way when they fully make it (but i think they will forget) but hey it is okay the game was awesome nonetheless enjoy the video!
