Wow. So impressed by how polished the UI, battle animations, cutscenes, soundtrack and pretty much everything is!
I also liked the battle sprites though they seemed a bit lower resolution than many of the assets. Could swear I've seen those battlers somewhere (though the main char was custom I'm pretty sure).
Mechanics were solid.
I really dig "health as a resource" in battle systems but I'd never seen it used as an exploration resource before, except maybe annoying damage floors.
The shield was a good inclusion to add a timing mechanic to the big sentry bots (unfortunately I didn't figure this out until burning 3 Health vials haha).
My only detraction in terms of the battle system is that using TP on non-boss fights is detrimental because you probably need 50 or 100 TP to use the alpha strike if it turns into a DPS race (which by definition it always is). Counter-intuitively, you get so many MP vials that MP is actually a pretty plentiful resource and TP is at a premium, which is backwards from most games. It's a pretty small and subjective gripe really, it was still tons of fun and next time I'd just use the MP abilities more.
