I was so hyped seeing this on the jam feed
It's a cool premise, would love to see what you're adding by the end of the grace period. So far I will say that the art and music are my favorite parts so far, but that's subject to change
I do agree that the combat can be a little simple in its current stage, maybe a reload system instead of a bullet pool that you slowly chunk through without reloading would help, in general some more mechanics on top of just moving and shooting
And SFX would really boost the quality of the gameplay - its tough to tell what's happening without them.
Lastly, I'm not sure if its something you can fix within the grace period since it might require NavMesh to really fix the issue, but Rissa and Fuwawa can just be hard countered by the environment colliders blocking their projectiles, but you can still hit them since they're so big, so there's no threat
But definitely let us know when the new build is up after the grace period ends so we can check out and rate the most polished version!
