Hello again NeatGames! Thanks for sharing your impressions - always enjoy, always appriciate :-)
Ambient sound is noted down - that's a nice idea, like it!
I'll check out your update soon. Spotted it already, but want to also get a second voice in. My nephew was playing the older version of YesterSol with such a passion. Will meet him at one of the next days, and will do the review together with him. Stay tuned ;-)
