Maybe an HP Prime or TI-Nspire version?

What is this palette? It looks really nice

I was going to work on portal this afternoon, but I found some old sprites from "Adventure" (a game I was working on but never finished). I started adding/editing sprites and got a bit carried away. Here's where two hours got me:Mockups:Unfortunately, I think these mockups are a bit dense to have good performance on calc. I do think that I'll take this project up again at some point, I already have several ideas that will make it more interesting, and easier to make as well.

that is nice. try decreasing the contrast on the background, though. right now it's difficult to tell the sprites apart from the map.
