Loved it! Early levels are easy but they ramp up quickly when introducing the irregular shapes, loved that. Will come back to complete the levels.
I am super curious how you designed the levels, since many of them can have multiple solutions. They play more to intuition than planning ahead, but puts them in the exact spot for them not being too difficult while enjoyable. Awesome work!
Thanks so much for the kind words!
Designing levels is actually much easier than solving them ;) I just stamp the shapes on with addition in any way I like, it's up to the player to subtract them again. It's thanks to the design of the shapes and the fact that subtraction is commutative (order of operations doesn't matter) that naturally leads to multiple possible solutions.
I did try to create interesting levels, not just random ones. I've found the truly randomly generated Unlimited mode to be much more difficult than the hand-designed levels.
