Bear in mind that MKF has not been abandoned. News and development will be trickling out slowly at best for quite a while.
All we can say is we are adding new content, as well as addressing existing issues the best we can. Our team is composed of multiple people who are picking up the slack. For example, we have active level designers churning out levels on a regular basis. A very promising newcomer by the name of Shodian has created some very impressive new levels, including a homage to Rice Beach from the first Wario Land:
He's even doing a Boulder Dash (NES) level, complete with remastered music and original Boulder Dash NES sound effects!
Another promising newcomer is Pouncer26. He's making a level jointly with another person based on Resident Evil's Raccoon City:, complete with Zombie Goombas and Umbrella Corporation blocks:
Another Pouncer26 level is based on the classic id Software PC game, Commander Keen. It's a level based on that game's level: Well of Wishes, complete with its original music:
Lastly, JudgeSpear has completed a level based on the first two levels of the classic Irem horizontal SHMUP, R-Type. It is called Bydo Station, and is the first level ever made for the optional World 6 (SHMUPS Domain):
We apologize for the lack of updates, but because several key members of the development team have other obligations, fresh MKF news will be slow to come by. Thanks for the understanding.
