As jonne said, it’d help to have some more info on the gameplay, like, some mockup screens or something, the general genre as well (I’m not sure if that’s a management simulation where you give order or that’s more an arcade one where you actually control a maid, maybe both?), some optional ideas (e.g. really messy, boss-like clients, different stats for differents waitress) and various things (e.g. clients have timer before they go away)!
I am interested myself -I have yet to do something on the pokitto haha- but my time is pretty focused on other fields so quite limited. Also I didn’t check the java lib, thought I should be OK with the language itself. I’ll try to make the visualization exercise for this game tho!
