Interesting concept! I do think currently the level difficulty curve is not that obvious, maybe is possible to start on a more cleaner and smaller map then slowly expand it level by level? It does seems a bit confusing when first loaded into Level 1.
Just a thought, I think adding sfx and eyes? (we need some numbers characters walking across the screen lol) to the numbers might seems fun. Nice game !
Ironically the design is actually opposite with fewer and fewer free pipes per level. Ie it starts out being like pipe dream, and ends being like factorio.
As for the difficulty curve that was a submission mistake . I put the first version up 10 minutes before the deadline and didn't realize wouldn't be able to submit more tweaks to get the challenge right. I'm glad I left something that is playable though the other alternative might have been to have a difficulty challenge so high you can never get past the 1st level.
