Really cool approach to making an incremental game. I can absolutely see this being developed further—with a few gameplay adjustments.
That said, I never quite felt like I was making meaningful progress, or even had a clear goal (not even something small like an upgrade). I was mostly drawing paths and occasionally placing upgrades—which, in my mind, felt a bit random and disconnected. The progression didn’t feel rewarding.
The core idea is definitely there, but it could use some thoughtful polish to bring out its full potential.
Still, for a 4-day game jam, this is an impressively complex and fully playable entry.
