The artwork/animation is absolutely lovely. The color palette & pixel work between both game and itch page made for a very cohesive design and it meshed well with the music. I found the disconnect between the war themed game play and the relaxing music pretty funny though.
I don't really have any critiques but I do agree with OneThatEatYou's pointers.
Truly, this felt like a complete game and I believe the only thing that stopped you was the time limit. As a solo dev, fantastic work!
