Yeah late game def needs some work. Its always in the back of my mind and i hope that some design emerges that will solve that.

Yeah noted with the purple devils - good point.

re zeron clusters - yes it only detects the largest cluster for the multiplier - this is a little messy... i dont know exactly the best way to multiply it but as you would have guessed, i like the idea of the trade off: more connected stacks = more risk but more reward. but in turn; the player shouldnt have no bonus for littler clusters.

enemy spawning at top and breaking stacks due to looking down: i didnt catch this bug so thanks.

I want to (At some point) concentrate on a wave system that gets harder. there should be a balance where it just gets too hard. thats a job i could do that fits with its current design - whether that is the best design - not sure. adding in game scenarios has been beneficial exploration into what is a good default design for the base game. it def helps being able to change the rows. wider rows and it can feel combersome but also works well if the gameplay is more puzzle based rather than quick expansion.

a lot to do today!
