I love games like this. The fantasy theme is great, and I love the art. However, I would've liked the text in the UI to not have such a basic font. I think using a different readable font that fit the fantasy theme would've helped it some, but that's just a minor nitpick.
The first thing I thought when I loaded into the game was "this game has no in-game tutorial". I tried to figure things out without checking the controls on the page because I like to give reviews based entirely off of my in-game experience. However, I got bored of spamming left click to kill an enemy with 15-20 hits multiple times. I feel like the number of hits it took to kill enemies dragged the game out unnecessarily longer than it needed to be. I think it would've been better to have a shorter game and have enemies feel better by killing them faster.
I didn't know I could cycle through spells with Q until the room before the final boss (when I finally looked at the controls on the page) and by that point I was mostly playing just to finish. But, it did get more fun when I had more control over what spell I wanted to use. Thinking about getting a random spell, I know the theme is "out of control" and I wonder "is that fun?" For me, it wasn't until I realized I could cycle through spells because I just felt like I was clicking for the sake of finishing the game and using spells just to finish faster, but the latter problem went away when I started cycling spells. I think the focus of the game should've been on using spells to make the player feel like an action-packed wizard badass. But as of now, there's a lot of downtime between casting each spell, which makes it an action game about how fast you can left click to kill things. I think killing enemies should help regenerate mana faster, or just have the passive regen be faster.
Overall, I really wanted to enjoy the combat, but the time it took to kill the enemies, the soreness in my index finger from spamming left click, and lack of in-game tutorial took away from it. That being said, once I knew all of the controls, it was very fun to dash around swapping spells killing things. I just wish I could kill enemies quicker, use spells more often, and knew I could cycle through spells before I got so late into the game.
