I thoroughly enjoyed this entry. It's well executed, has some deep systems at play here and although I generally dislike first person view battles, this one is handled nicely and I had no qualms with it.
The graphics are nice, mapping is nice although I do think the dungeons could use a little more personality. I'm not too sure if they are being randomly generated or not and whether it's even possible or not but a little more decoration/things to see would be nice :)
The menu and overall UI looks good and is intuitive, the icons are clean and easy to get information from. Overall the aesthetic is pleasing :D
In terms of mechanics there are lots of systems at play here, very much a deep game and I can really appreciate that. I did find that the introduction of many of them so fast was a little hard to digest for me personally BUT I understand you want this information out there so the player can get on a see the potential of the game. Highlights of the mechanics for me were:-
1) the Weakness system, easy to remember and stops you from spamming the same moves making combat much more tactical.
2) The blind state- very cool (don't want to elaborate in case of spoilers)
3) Speed tier list - again, very nice addition that adds much more tactical combat
The other systems, like XP and skill collection are handled well and all come together to make it fun to play and quite addictive.
From what I played I didn't see too much of the story but it seemed intriguing. Writing was fine and delivered what it needed to.
There is only one thing I didn't really like in their current state and they were the traps. I felt these were quite overpowering, especially the HP/MP ones. Quite often these would knock me down to very little HP and MP and I would end up dying in the next battle. Think these could be tweaked or at least, a different system put in place to either make traps more avoidable ala perhaps a quick time event or dice roll to either avoid the trap or mitigate some of the effect.
Also, would have been nice to have some battle music for the mob encounters, I know it's not much but I missed it :'(
Overall though, a solid prototype that I can see much potential in. Executed well and I had a lot of fun playing it, great job :D
PS: Obviously the battle animations are top notch, but that goes without saying ;)
