Hi guys, long time no see. Time for another mini project.

The portals in the game actually affect objects other than sonic - to the extent that you can kill an enemy with its own projectile if you fling it back at it.

I attempted to recreate the portal gun as best I could, but it turns out the sonic engine isn't a huge fan of warping. You can probably break the game in many unimaginable ways, but I think I covered all the major issues.

I am posting this now as I'd like to focus on another project. However, I would happy to donate the source if the community took this and made an actual puzzle based game with custom levels using these mechanics.

Many thanks to E-122-Psi who agreed to build this fantastic spritesheet.
