I have a strange complaint which is that the game is too... deep I guess? I enjoyed throwing the elements around but the combos and iteractions were largely lost on me because there was just so much stuff going on. I got style bonuses, the enemies got style bonuses, there were AOEs constantly spawning in around me which seemed to actually be on my side(still no idea why small elemental circles spawn) and in the end the only interaction I figured out is that wind spreads fire. I also feel like the filling circles around the character mean something and they seem like an interesting interface choice but I didn't figure out their purpose except for the ult one(same goes for extra healthbars).
So overall I'd say that the mechanics seem deep and complex in a good way but the pacing doesn't let you engage with them at all because from the srart you are surrounded by a lot of enemies that demand getting rid of, not experimentation.
Now I've wrote 2 paragraphs criticising the game but I look back at the rating and it's one of the highest ratings I've given yet just because of how much potential there is in the underlying systems.
Also the compendium is a wild thing to add in a 7 day jam and I really enjoyed reading it!
