Super Mario Bros + Portal
Here's an awesome Super Mario Bros clone game with a twist: It's got a Portal gun (ASHPD)! Yes, that's right, you can warp around the levels as if you're playing Valve's Portal. This neat SMB game is coded using Löve, a free 2D game engine. The author plans to release the source code after it's complete. Here are a few highlights:
* Original SMB Levels and Lost Levels will be included
* Simultaneous Multiplayer (4 players on the same screen!)
* Ingame level editor
* Ingame downloadable mappacks.
