I got the basic engine for level 1 working OK. It took a ton of rebuilding and retrying in Stella, but after a few hours of missing, it finally decided to work. Right now, you can only go right. And the ledges just loop over and over again. As for enemies, I'll have them be shots overhead from the aliens trying to make Zeke sober, since both players are used to make Zeke. I may try to go forhim being made out of only one player, but not for now. I tried it on my Harmony cart, and amazingly, it works great. At its lowest cycle point is 512, so I should have room for music and simple enemies. If you fall off a ledge and die, it just resets to the title screen. For those who are wondering, yes, it bears a striking resemblance to the celery game I never completed. I've just replaced the celery with Zeke. And also, I plan to redo ledges so they change, but, like Super Mario Bros., the setup will be the same.
