Awesome job! I really liked the past/present facet of the game. I liked how the Fiery Passion of youth was literally demonstrated in his magic, and as he aged, the magic became much calmer like water. That stuck out to me. The upgrades were cool, I didn't expect the old man to get any! So that was neat.
It played a little sluggish, and the momentum-based movement may have been better switched with a set speed instead. (getAxisRaw instead of getAxis, for example) I did get lost for a bit, and due to the movement issues, it was a bgit of a slog to get un-lost. Maybe more distinct areas/minimap would have been great (time constraints limit these polish-decision, I understand!)
Boss battle music! I'm glad you had a boss. It was easy to run and spam fireballs, almost incentivising you not to use the sword at all the whole game (with the old man even saying how heavy it was) but the intense boss battle music was a nice change. The other songs were a little grating after getting lost, but not too bad. Again, time constraints limit these things. I would have loved more music. Still you had 3 songs which rocks.
Awesome work in a month. Seriously.
