I lost to the cellar chaos boss, but I got a completion message anyway? I'll take it, the celestial dog already gave me a run for my money. ^^'
That's quite a lot of content; I know quite well how once you get past the core mechanics implementation adding levels/items/enemies/etc. becomes relatively fast, but still, it's quite a lot - especially with all those enemy portraits and shadows and other graphics. The tutorial might have had a tad too much text at once - would be nice if player input was permitted in the meantime, or some explanations (like matching element affinities) were pushed until they became truly relevant. Still, there were quite a lot of mechanics, and it was interesting, having to balance skills so that they target the affinity, but also don't defeat the enemy too early.
A little nitpick - I'd prefer if I could speed up the dialogue typewriter by clicking once, and then clicking again. In the first place, the typewriter effect feel pretty redundant if you interact with pre-written text, rather than speaking people. ;) But those are details.
Pretty nicely done, overall; some mechanics could be polished here and there, but overall the game has nice amount of depth and content to it. ^^
