This a free full puzzle game about Marcus O'Snail, a friendly snail who is abducted by scientists and forced to navigate through mazes all day long.
The game including all assets (music, sound effects, art and code) were all made using only a smart phone. If someone is interested in how it can be done feel free to ask me any questions. I'd be more than happy to share and discuss workflows.
