I am a part of Gingerloaf's team (as abon.art) and agree with him.

If I ignore the message in game about depression, I think this is a great game about a child defeating the monsters under his bed with his mighty flashlight.

As I play feel overrun by sadness and anger. Defeating enemies with a flashlight felt weird as my happiness meter went up while I didn't feel any progression of getting better.

Spreading awareness of depression is a great thing however as someone who has gone through depression and has come out the other end, this game doesn't spread that message well if at all. If I didn't have sound on I would have assumed I was killing monsters under my bed.

My feedback is split into two parts because I believe that spreading awareness about depression is a good thing, but is not necessarily joined at the hip to this game or it'd design.

The game:

1. I never really felt like things where getting better. Maybe portraying happiness as brighter lights or happy songs or happy objects appearing in the room. I felt like I was constantly overrun by the blocks the entire time. This could be a good representation of depression but not necessarily a good representation of overcoming it.
2. Not entirely too sure how light (from a flashlight) plays a cohesive role in the theme.

The message:

1. I think spreading awareness is a good thing, but maybe focus a little more on getting back to the good than being overrun by the bad.

It's tough to make a game with so much meaning so fast. I think you are on the right track! Keep it up!
