Nice work! I really enjoyed playing and it took me a handful of attempts to figure out the best way to manage my spells and avoid dying! The presentation is nice and I liked the fact that you could pick up new spells along the way to help you make it to the end.
The unique mechanic of straining your memory to clear out active spells was pretty interesting, and I could see it being really cool if you were facing enemies with different weaknesses, etc. This game definitely seems like it would have a lot of potential as a roguelite or similar.
One thing I sort of missed from other turn-based games was the ability to visualize/target attacks. Sometimes I wanted to hit an enemy that was “in range” but it wasn’t feasible without moving into their range of attack. I think allowing the player to aim some spells, or just showing the area of effect might have made it feel a little more intuitive.
Overall great job though, really enjoyed playing!
