In there you will find screenshots, a demo for download, and a lil bit more.
He just posted new screenshots of the game up in the screenshots, and a concept title screen. He would like your opinion on it, and will hopefully have a few more up soon, which he will probably start a poll up for.
I don't usually play ASM games, but It does play good on the emulator so I would guess it plays just as well on calc. It looks like it's coming along nicely.
What did he use to program it? the Ti SDK or TIGCC?
TIGCC as far as I know, and there are few, if any bugs on calc. I have played it many times on the calc. The most severe bug I found so far is that the tail does not end up in the same spot when starting a new level...
But otherwise, it almost plays like the original version did.
