I always have a soft spot for RPG Maker, so I needed to give this one a try.
Pros:
Everything works and nothing is broken (this early in the jam, a real accomplishment!)
The two party system is pretty well balanced.
I never got lost with where to go. I liked the little sparkles to act as a signifier.
The movement of the sprite battlers was great!
The interaction between Flor and Azuli was intriguing, but there wasn't too much there (mainly because it is demo! I say intriguing, because I think your longer version will dive in much deeper!)
The introduction of the Corptube plot seems like it will make a cool mechanic in future games.
Things I would like to see added:
I like the RTP and won't detract using it at all, but I do think using the RTP with screen flashes and tint lighting really makes the ascetics look more dynamic.
Some of the scenes transition very quickly while using animations, and I would normally let the animations play out with a 30-45 frame wait to give a little more exposition.
Overall a good submission and a quick, good impact! I've made a few magic girl games with RPG Maker with a lot of RTP, so seeing someone else do one with RTP was nice!
