That's a good topic.
For me it is not exactly the mechanic that is fun/cool, but the context in which a mechanic is used.
By that statement I can also find jumping and double jumping fun.
Speaking of that, I am just making a minimalist game about mastering strategic platforming as an engine test, there is just jump and double jump. I have fun with the little game:) I made a short render test, would be interested to know if it also looks like fun for others.
It looks fun, but I'm concerned that the player won't have enough time to react to the falling blocks. I would make sure to test for that.
EDIT: I'm an idiot. I just realized that the blocks automatically fall where you are, and it becomes a line clear puzzle game. That's actually really cool. If you ever have a playable prototype, I'd love to try it out. You can email me at
