Quite a nice idea that allows for a bit more complex management than many of the more intensive looping games I've played. The flow state was very nice and I felt the intuition of the objective was pretty straightforward. I did feel there needed to be a bit more push and pull, or at least something to let me know if I'm not reaching my maximum potential of output. I felt the pickaxe was also underdeveloped as it seemed way more worthwhile to just wait for spots to clear up - accidentally using it wasn't much fun. Very polished otherwise.
You guys seem to have a love for gardening with this too.
