This is interesting. I only have the bridge tool so far. It is very grindy with a lot of resource scarcity.
There are the occasional expeditions where you are dropped between letters which can be really irritating. You can't seem to ever teleport quickly enough so lose half your resources. It was the 5th or so time that happened when I had 11 white gems and 4 red ones, trying to unlock the paint roller, that I decided I was done.
If you spam the teleport from an expedition you can teleport from the ship. That didn't break anything, though.
I did find getting hung up on pixels as you were digging to be a little frustrating.
I did encounter a strange issue where when I dropped, I was embedded about 15 pixels below any surface. That made for some unrecoverable situations even with a bridge as I was embedded in the bridge and would ultimately fall. Getting embedded was fixed by a refresh.
