Okay, I’ve got several ideas that didn’t get off the ground yet, and you can see a couple of them on my Creator’s page. Ranger is a remake of DOS Airborne Ranger game, a lot like the original Metal Gear game for the, I think it was, MSX. Sleuth was a super simple DOS game that desperately needs remakes of any shape or kind. I’m aiming really high with these two, way too high for a game jam (I learned the hard way). Plus, I’ve been stalled by my novel… Anyway, feel free to do either idea, the world has room for two of each!
I’m just gonna do some kind of pixelart game and try to make it run on DOS, perhaps using https://github.com/rx/lovedos or the Vanilla Lua at archive.org or else with FreePascal’s DOS cross-compiler.
Additionally, there is a mario-like set of tiles on itch called 1985 (or 1984) and it would be great for a DOS-type game.
And, you can never go wrong with a vertical SHMUP, that’s my philosophy! :D
