Thanks for playing! It is all procedural. I'm aiming for a big number roguelike rather than a puzzle but it's still missing the big aspect of tweaking your deck of buttons and upgrades.

I was thinking that maybe a Star rating system similar to candy crush or overcook might be a nice incentive. Where 1 star gets to to the next level, but 3 stars help to boots the gamers ego. That works great with loose point base challenges. But it would need to store previous game and allow replay though. Something to get the player hooked.
