Really good, hooked me in so much I ended up playing through the demo in one sitting. The music is nice, even if the battle theme can get repetative at times, and the various flashback battles change up the pace and keep things interesting. The writing's good, only found one typo at the last dev message, though punctuation could use a re-work at some places (extra commas where it feels like they shouldn't be or missing commas in place where they feel like should be, missing periods at the end of sentences etc.). Slow is really powerful once I notuce that it's cumulative, Mosca's AOE slow spell can halt enemies to a literal crawl. Her Rock-Paper-Scizzor skill didn't seem to do much either, at least not what I noticed, and Finnegan's cleave skills seemed mostly useless since 90% of the time that move is used as a finisher (as by the time you have enough MP to use it the enemy's health is down as well). Other than that, skills seem fairly balanced and with the stats can build around different strategies. I've only encountered 3 bugs: In the house, the boundary of Haydn partially blocks when you try to click on Finnegan (most noticeable on the chest area) One time after being defeated on a split path, instead of redoing the node I was on the game only allowed me to select the other node instead, then after defeating it the available node switched back to the original path (screenshots: https://imgur.com/a/EztnOtu, you can see the helmet is at the top, then jumps back and the ! is back on the top) During Mosca's dream sequence, I did the first 3 teleports from the top, but the path was lighting up white for nodes 1 2 and 4 instead of 1 2 and 3.
Still, really good game so far, looking forward to see where it'll go!
