I found this game to have a lot of interesting ideas, but it didn't take full advantage of its potential. Dr. Mario with combat elements sounds good on paper, especially since Arkanoid did a similar thing to the Breakout formula, but there are several issues with Dungeon of Elements. For example, while there are many normal enemy types, they only differ in terms of appearance and potential loot; they never move, they never interact with the alchemy pills nor the board, and they all die in a single hit. Boss fights likewise tend to simply devolve into tedium as their abilities are usually defensive in nature, such as teleportation, invincibility shields, and/or some form of regeneration; the few bosses which actually pose a threat by creating and moving units are all fairly early in the game.
Obstacles on the screen are another element of this game which sounds good on paper, but in execution they are sometimes hard to see and at other times (sometimes deliberately) they hide enemies; this isn't so much a challenge as it is a struggle with the aesthetics. Pits which pills can fall into are another interesting idea, but they are rarely anything but beneficial and this leads to one of the bigger overarching issues at play here; the player is given a ridiculously huge advantage from many of the unique aspects of this game. Weapons have fairly length cooldown times, but can devastate a substantial number of enemies in a single hit, even the earliest boots in the game slow down pill drop speeds substantially and shields temporarily slow it down even more (though I never once needed to use my shield until the very final set of stages when playing on Normal and Hard is only unlocked upon completion of the entire game), and crafted consumables range anywhere from large explosions to a pill which will outright kill every single non-boss enemy on the screen.
There's plenty of content here for anyone who *really* likes the Dr. Mario formula and there are many interesting mechanics present, but Dungeon of Elements fails to take full advantage of its systems and ultimately comes across as being a case of quantity over quality and simply ends up feeling repetitive.
