It took me a while to complete all the game, which is a good sign for a game jam entry, it really hooked me enough that I wanted to finish it.
I thought the atmosphere was amazing, the art and music really capture the vibes of the Dune universe,great job there!
I also thought the game loop was well-designed, each section is just the right length: not too long to get boring, but just enough to leave you wanting more.
Things to improve: In the initial tutorial, in my case, it tells me that the map is accessed with the letter “Ñ,” but the interface says “M,” which is a bit confusing.
It would be nice if when the Elder gives you a clue about a square without the water source, it were marked somehow on the map, since it’s hard to remember every single square.
I’d also try to improve the enemies pathfinding, they sometimes get stuck.
I understand that you’re already aware of all these things, but it’s not easy to add everything when the jam's countdown keeps ticking away ;)
I think your project has enough potential to keep it going and not let it die after the jam.
Great job overall. Congratulations! :D
