Thanks for the feedback. I am actually a Commodore kid, but M.U.L.E. got me appreciating its typesetting more than the one built in the C64. Your interest in the game as well as someone else's recent comment makes me think I should pursue this project as an actual 6502 game.
This game was very much inspired by Jumpman and Loderunner. The idea came to me while brainstorming for a game jam--but I didn't develop it until later. I forget the jam theme--was probably something like "between worlds". And I had this idea of phasing between a platformer and a tile based game. I'm sure you could come up with a lot of ideas to make this combination fun.
I love truly retro games. I'll check your profile and website. Thanks!
