Fun little game! Almost missed the actual ending since I looped back to the start and didn't realize where I needed to go. I liked how you implemented the little "bosses" and they all had different behaviors. I also really enjoyed the whole use of light! I know I need to learn how to use lighting and such.
I'm not sure what the orb powers actually did unfortunately but I did think it was cool to get upgrades esp for the attack!
One suggestion would be to keep the torch lights on, but provide only a little light. A portion of the game was really just "memorize where you need to go and walk in the dark" which is a fair challenge to present but it didn't always feel fair. I think what would be better is to leave the torchlights on, but if you take the orb off then they only produce a small amount of light.
