Hey, thank you for trying out the game even if it wasn't your type!
I do actually agree about the wait feature - it's definitely a great quality-of-life feature, but it also wasn't absolutely necessary for the game to work and it does make the game more complex. I think I ended up adding it to prevent softlocks and any frustration!
I will say that the spaghetti code disagrees that it's expandable, but multiplayer sounds very interesting. What did you have in mind for a multiplayer version of this game? In my head, I'm thinking of some pass-and-play mode now, where the board starts filled with enemies, and during a player's turn, they can either remove an enemy from the board or try to do the level to score points. Maybe everyone has a set amount of attempts they can take, and that the highest score at the end wins.
A story mode would also be interesting! It'd be a fun challenge to see how to implement it considering the random generation - and, well, what the story would be, of course. Something about gathering colours, I'd imagine.
Thanks you for your feedback!
