I like those games where spellcasting is broken down to different components, so the gameplay here was very appealing to me. It was a bit difficult to understand how everything works, but I think I got the gist of it after 2 deaths. I think changing the font to a more easily readable one and/or making use of some icons or color coding (or something similar) would help a lot to get a grasp of what's working well and against what.
I wasn't sure I made the best decisions, I was trying to get more dice because it looked like I can't keep up the pace with the enemy, but the dice I stole weren't very useful when I used them. Are the numbers rolled each turn randomly or is there a limit? I never seemed to get anything above 3. While the enemy seemed to have an endless supply of dice, I always ran out. Is the intended way to play to steal a lot, and if so, if it better to steal the numbered dice or the elemental ones? This is not a critique, I'm geniunely trying to understand the tactics here so I can come back and enjoy it with a bit more success. :)
The visuals along with the subtle music worked well to create an arcane atmosphere, and the controls were easy to use in general. Aside from the minor nitpicks above regarding the UI and guiding the player a bit more, it was a well rounded experience, impressive for a solo dev.
