Hi thanks for playing the game, glad you liked it! Yeah it was quite a pain at the beginning to figure out how to delete the tiles from the tileset but I'm really glad I was able to eventually figure it out. Adding upgrades is a good idea for the dead-ends, the way I thought of it at the beginning was that the end game upgrade for digging would be so OP it would account for it (and since I made the paths and stuff well before I added darkness and lighting I never accounted for people getting stuck in the deadends as an actual possibility when so low on time XD sorry about that)
