I got to age 15 until I raged quit - I am a bad parent.
Things I liked:
- The gameplay works perfectly as metaphor, I genuinely felt responsible for the child and I genuinely thought the child was going to kill itself around any corner.
- Age 15, that one bit where the child bounces through loads of red spikes, but misses all of them: this is a great example of the paranoia of being a parent.
- The cancer wall scared me. I wonder if, rather than a large wall hitting you, maybe this could be represented by the pink character fading away slowly by tweaking the alpha value?
- The art style in the first scene is great, with the felt-like textures, you should've kept it all the way through.
My main critique would be the physics of the child and the parent. The child doesn't bounce correctly, which makes the game unfair. If you were to make this again, I would spend longer making sure the child has more predictable collision physics.
