The game feels rough to play at the start since the player needs to dig 2 blocks wide to move down and 3 blocks high to move horizontally. After getting the area size upgrade, the digging felt much easier, but I feel like the player should already have one area size upgrade at the start, or at least make the upgrades all much cheaper for the first purchase so that players can experience more at the beginning while still enjoying the grind. It definitely became more fun after obtaining the first few upgrades after some time. :)
