Wow super cool concept and executed really well!! Love the music, the soundtrack was excellent, and I liked the visual style you brought to the 'wish orb'. Really nice work on the whole UI and interactions.
I'm not a big puzzle gamer so the tutorial was kind of a lot to absorb all at once, but I managed to figure it out after a bit of trial and error. The reference chart on the left was really helpful. I was a bit confused about unlocking elements and so I used the 'Refocus' a bit too much at first, but then I found out I can unlock them by combining nearby elements. Still kinda difficult to do everything I needed to do before the enemy attack phase, so I didn't survive super long. I also had a bit of trouble figuring out the multi-colored element for the magic missile, but overall it was easy to understand the spellcasting mechanic which was really interesting!
I liked how there were multiple avenues to attack and figure out the optimal decisions based on the enemy HP. Do I go for a straight attack or use a few turns to charge up a spell? My only trouble was resource management and keeping the board unlocked. Quite a challenging puzzle game!
This is also a small detail but one animation made it harder to follow what was happening on the board as the combining wasn't happening where my cursor (and therefore my eyes) were focused. This might help with readability to show the combined element exactly where the player is already looking, then slide in the orbs to fill the gap (mockup of my suggestion vs how it is in game currently)
My only other wish was that the 'wish orb' tiles acted more like wild cards that could be used to cast any spell! Right now they felt a bit more like a dud/blocked element since I didn't have any spells that could utilize them.
Awesome entry and great job!!!!
