Sorry that I haven't updated the Pre-Alpha build though I'm debating if I should have called it a Demo cause the build is just a tiny piece of what the entire game is gonna be.
Anyway, most of the current work on the game has been mostly in documents and concept art forms, so important stuff for the game, but not really stuff that players can witness or see much of. Also, gameplay-wise I'm experimenting on a possible grid base style movement for the game much like Frogger (I mean both characters HOP around the level), but not 100% on it and don't want to update the Pre-Alpha with that new form of movement, until I think it works for the game and people are fine with this style of movement, and the movement system is properly programmed in the game. Lastly, my birthday is coming up so will, of course, give myself a day or two off to celebrate and such.
Not sure when the next update will be on the Pre-Alpha, but currently my partner Tsinji is working on some character artwork of some of the characters that are planned to appear in the main game and hopefully in a few days will share them to everyone soon.
