Okay the credits were super cool, kudos on that detail.
I enjoyed the visual style, really takes me back.
The sound was a bit too repetitive and didn't seem to convey much of the grandiosity/action.
I made a pacifist run of sorts, avoiding conflict with monsters because combat was too hit-and-miss for me. Also, although the movement felt a bit janky with the floatiness, sprinting around fixed the slow move speed.
I enjoyed seeing the world diminish as I got bigger and bigger soldiers, was just a bit odd to see new bigger monsters around when there were none before, but that's nitpicking I suppose.
Some doubts: what was that "I'm also here" guy? And the scary head above my soldiers at the end?
Overall, it was a nice idea! Congratulations!
