You can only place tiles adjacent to existing tiles. Additionally, you may only place hex pipes on hex tiles and pent pipes on pent tiles. A agree a better tutorial would go a long way :) Thanks for playing

Thanks for playing! The goal of the game is to get 3 pumps and 3 exhaust ports on Europa at the same time, but then that's about it. I unfortunately ran out of time, otherwise I would have loved to put more content in. If I turn it into a full game there will be plenty more to do :)

Thanks! Yeah it was a lot to try and get done. I'm just psyched I had time to do it.

And yeah the I tried to get the pipes to spawn in a semi-random state. So it will give you 3 ended pipes, exhaust ports, and pumps in certain intervals. But that's never communicated to the player and the system in general has some flaws. It's definitely where I would focus a lot of my attention if I were to build this out more, as its pretty much the core driving force of the game.

Shoot. Will correct promptly. Thank you

Build has been updated and should work as expected. Thanks again for the heads up.
