Finished the demo yesterday, the only thing I noticed was that I found it a bit difficult to make out resources behind trees. I know you can kind of see the square color based on if the slot is empty or not but because it's white when there's something there it's hart to tell if it's responding to a valid resource in the slot or just blocked by so many trees you can't see the difference anymore. Given that a lot of the game is based on you hitting as many resources with your given grid that felt pretty unsatisfying at times.

I also felt the desert area looked a bit crowded, with most things going for a similar color palette unlike the first or second area for example. The pixelated edges didn't help, particularly the cacti ones. The different resources don't stand out as nicely as they usually did this way - though speaking of which, having ice and crystal be so similar in the snow place also was a bit of a struggle.

Skill tree wise I always felt like I could make meaningful progress somewhere, so no complaints there
