Using the sprites, music and general design philosophy from all three SNES Donkey Kong Country games, modder DooMero has crafted a brand new DKC in the Doom engine.
You can check out a long play of Donkey Kong Country DooM on YouTube, and the thread detailing the making of the game on the ZDoom forums.
This is impressive work, for a number of reasons. Taking an aging engine designed for 3D games, and using it to crank out a fast-paced 2D platformer is no meant feat. But what DooMero really nails here is the feel of the older games. They've remixed enemies, music, and environment art from all three games in new and inventive ways. And the level design is pure DKC, meant to evoke a zany obstacle course full of big-eyes creatures, rotating barrels and disappearing ropes.
It's "just" a demo, but it takes DooMero about 42 minutes to finish, and features 10 levels (as well as a very special boss battle.)
The demo is available for download now. You'll need to have the latest version of GZDooM to play.
