From my experience, the enemies at the beginning are too easy, and the the second enemies (I didn't get to see any more) are too hard. If they see you, you're dead, I couldn't do anything. The digging is quite tedious and the shovel upgrades don't seem to do anything no matter how many I get, on the web version. I went to the PC version and tried again, which worked a lot better, but then I got trapped in the second shop, and no buttons worked. Not sure what caused it, I was rushing in, pressing Shift and W, but either way, I was unable to finish the game, if there is an end. Don't take this for a bad review, it was enjoyable, I just would like to address the problems I found. It is impressive for the amount of time we had. Well done.
