Retrush is a speedrun-focused mappack for Mari0: SE. Each level has eight time gates that give Mario a short time to reach the next one.
The mappack is still in active development after several years. Sixteen main levels are planned, with an additional "Red Coin Remix" challenge for each (for a total of 32 levels). A public demo with four levels was released on the forum in 2014.
- Its title is a portmanteau of "retro" and "rush".
- The mappack was originally going to have 12 levels (with no extra challenges), but WillWare doesn't know when to stop.
