I might be late on posting this but...
This is Sonic Xtreme: Construct 2 Edition: https://www.scirra.com/arcade/adventure ... ition-1100
The game is a 2D Sonic fangame based off of Sonic X-Treme, a cancelled Sonic game. It will be like the classic Sonic games. You'll go through the levels from Sonic X-Treme plus some original levels. The game will use music, textures, and sprites from Sonic X-Treme and any other Sonic game.
I am currently working on Alpha 1.5.0, which will have more levels, more animations for Sonic, and a new boss battle.
So far I have 3 levels completed: Jade Gully, Crystal Frost, and the final level which I have no name for.
Please note that I am using the free version of Construct 2 and I am on my 89th event. So expect for the next few updates to be delayed.
If your going to say something like "OMG dis game suks" or "Some1 git vinny, cuz dis game sucks!", then I won't respond, I'll just quietly remove your reply. I don't want to start a flame war.
