Cool idea for an endless runner, but execution is lacking. I did not expect tree saplings were dangerous. The up and down buttons are fairly unresponsive, with no audio feedback, and I'm not quite sure if it's an issue with my keyboard, but the time-change mechanic occasionally fails to occur. I also expected that just tapping the key would trigger it, but it seems to only trigger when you hold, which is a bit unintuitive. There's a lot of potential, and I'm sure you can improve!
