I think the game is great.
I've caught the things the haters are saying, and it makes no sense to me.
I think think the teleporters need a better description, as one-shot implies you can use it once.
Instead, you place the beacon and use that spot until you place another someplace else.
I think the map happening to extend a block further than the visual perception of the miner is also worthy of comment, as it's a useful feature. Strengthening the sonar as another upgrade would be nice, I think.
Overall, this is quirky fun and I recommend it for anyone.
