I've looked everywhere for some nice open source games for android. Specifically a 3d labyrinth or isometric view maze, like this

or a Unblock me game thats open source, like:

or

even just the basics would be fine, as im just an 3d / 2d environment artist, so dont know much about code

Hope someone knows where I can find anything similiar to this or any other "3d" view / isometric game thats open source I could play with (meaning mostly the artistic side of it , new sprites / images or models ofcourse "

Thanks for any answers, hope I posted in the right place as a first time poster and hope the images was okey.
