This is the first time I hear about the Wonderland Engine. I did small game projects in many 2D and 3D engines, frameworks, and pure programming languages.
How does the game check if you've a match? There's a similar game that I saw about matching four on YT, and they programmed all winning conditions in the game! There must be a more elegant solution.
I'm in the process of uploading a couple of games I made. Check them out.
