Very nice unique take on the time theme! Probably the most original that I've played!
It took me awhile to realize that my "time" was tied to what I was shooting, once I did, the combat got a lot more interesting of trying to prevent wasted shots by not having my time get full in either direction.
I found it a little difficult at times to really know which direction I would be sending myself, or my enemies. Mostly just became left click -> right click -> repeat, without knowing which direction they were going.
The music changing depending on your age was brilliant! I love it when games have adaptive music.
Having your character change mechanically was also cool, being younger to move faster and older lets you move things around. There is a lot of depth here for more concepts, like maybe being younger you would also have less health than if you were older. Having more objects change their effects depending on what they are, like a larger tree that can give cover when grown.
Very unique and cool idea! Could go pretty far with this!
