Enjoy


Apparently you can play through the entire original Super Mario game.
Fun for a bit but the Portal style levels included held my attention for a lot longer.

YES How long has this been out? Last time I checked, it wasn't released yet.

Captain Sparklez released a video on it in the last few hours. That's as much as I know.

2-2 of the portal style level better not be too long. Grrrr. Lost my 3 lives really quickly on it. Have to start again.

I knew there was a gonna be a thread on this game Shame you can't save though, or at least have an unlimited lives cheat.

The game appears to be updating regularly. Now there is a world selection and I think there always was a saving system.
There are also map packs made by users. Hopefully these will come flowing in soon.
I'm planning on making one myself.
