Bit By Bit Games now offers free downloads of Trail, an experimental, minimalist platformer developed in under a month as an entry into the 2102 Independent Games Festival. Here's a trailer from the game, and here's a bit of the description:

Trail is an experimental, minimalist platformer, which was inspired by a child's belief about death. Trail explores the idea that you leave a trail in the world as you journey through life and when you eventually die you need to collect this trail to achieve final peace.

In Trail you play through a level forwards and then backwards from the point of your death.

When you are alive, the world is white and you drop a trail of memories behind you in the environment. Each memory you drop increases your score. If you touch a memory when alive it hurts you (sometimes it's painful to revisit the past).

The level is your life, so there does come a point where you will die - there is no escape, no-one is immortal.
