Great visuals! Very impressive for a 48-hour jam.
The Concept is well done, fits the jam theme well. I really like that the best strategy for survival isn't to grow more, but rather try to prevent the conflict in the first place, although mountains are way too overpowered.
If there's one thing, I would recommend adding to post-release or any future game is a good tutorial. Walls of texts are way better than nothing, but showing which tiles you can use which ability, disabling abilities you can't use and adding easier levels that teach each mechanic one by one would be ideal.
Linux version crashes for me randomly, honestly, it might be a Godot 4.1 issue for all I know, so I won't judge you for that.
Couldn't really go very far with crashes, but it's a nice concept with great visuals.
