Maybe you should add a bit more info about what you need like:
What engine, C2 or C3?
Should it be a simple template to show how the logic works or a fully functional clone?
Do you want nice assets included or just placeholders you can change?
Should it be optimized for mobile devices?
The concept is super simple and is very easy to make.
That took me less than 10min to make. It isn't perfect but the logic works the same way.
C2. A template with all the functionalities (the loop block, been able to swap blocks, when there are 3 blocks, if you grab the 2nd one the 2nd and 3rd come together, the 1st stays, the blocks "detect" each other from a distance, etc ), every mechanic copied. I then make the levels.
Placeholders and then I change it. Touch controls should be enough for mobile.
The demo looks nice, but the pieces have to be dragged, should be able to be rearranged, and the loop block is missing.
Thanks, let me know if I'm missing some info.
