I gave it a few attempts.
Not bad if this is your first tower defense.
It appeared that the cost of connections increased by 5 every time one was placed. The game could definitely benefit from a description on the itch page to claify this to players.
Having just one life is brutal though. And the waves appeard to just continue after I got the game over message.
Thanks for playing it, and the good feedback! I'll update the description to make it more explicit.
The cost of the towers was a deliberate thing to try to balance the game. The idea I had for the jam initially was that the power grid would only be able to hold so many towers, so there would be relays like boosters or switches that allowed the power to be diverted. The increasing cost was my compromise in the time frame so that there would actually be a challenge. But even then I worried there would be no real challenge because the tower placement is all by necessity. "What can I turn on at this moment that will help with this wave?"
It maybe was a bit too brutal for a jam though. But with one day to go I was despairing because I had all the pieces in place but there was no player agency at all. Either the player got overwhelmed or built up an overpowered defence and there was no challenge.
Balance is harder than it looks, right? I had similar concerns in my game, fearing my puzzles would be too simple.
Perhaps you could test how it felt if there were more towers to each node, and once you powered the node you'd have to select the tower you wanted to activate. Perhaps pay slightly less per node, but also pay for towers?
