Absolutely charming.
* The art, music, theme, and UI all come together brilliantly
* A subject near-and-dear to my heart, totally apt to the theme on several levels
* Interesting puzzles
* I definitely didn't try three different times to beat the dragon.. definitely not
I do have a few critiques, though:
* The indicators for some of the enemy abilities could be clearer. I still don't understand what the dragon's fire attack is going to hit. A hover-effect (like hearthstone, into-the-breach) would be fantastic just to see exactly whats going to happen
* Knowing exactly who the healer was going to heal would have been very appreciated. I'm not exactly sure why, but it never seemed to go where I thought it would. Another indicator (like above) would be great
Top marks. This is solid work, excellent submission.
