This is really impressive. the audio is amazing, great art and well made gameplay.
Minor pointers:
I think the hitbox on the dragons should be a bit bigger, sometimes it looks and feels like i hit them, but the arrow just goes through
I did not understand first that the clock in the top-left was a clock. My recommendation is to format it HH:MM instead of HH,MM.
I think the minutes went up top 100, not 60
Well done!
