I think prize pegs are broken, instead of giving me the reward they instantly pop with no reward, even when having the multiple time prize peg on. Other pegs don't get instantly popped.
Edit: Also just after I prestiged, the buckets at the bottom now have infinite uses and change value each time.
A small suggestion I might have is the ability to flag according to the mine/enemy you have. Being able to simply flag an enemy with 1/2/3 with their corresponding number would be a really nice feature.
You need to connect the "START" box towards the "MOVE" box, not the other way around, because the code will go in a specific order based off in what order you connect the boxes.
