What language / engine are you using? I may be able to offer some help if I know it...
Our programmer used Python with Godot I think, but we have no access to his code, so it would be made from scratch anyway.
I'm not a programmer, but I think the game concept itself is pretty basic and simple, because our programmer whipped up a demo that is close to the finished game in about an hour or two.
If you want to help, you could basically use whatever language you want. Bonus brownie points if it's something like HTML5 so the game can be played in a browser, but that's not a must-have.
Thank you!
