Love this game! I played the first three mountains and had a great time. Slight shame that the demo doesn't have a save, but that's ok. I'll play again in a couple of days and do more mountains. It's a really cute game. It slightly reminds me of a short hike, it's different but feels equally relaxed.
Also, really nice controls as well once I got used to them. I had a bit of a dumb moment until I realised each mouse button corresponded to an arm.
Hopefully you're planning a full release? Any vague timescale?
