Finished with 32 points. I really liked the map, thanks for your work
I don't know if someone told it before, but you can fix the minecart puzzle placing some powered rails instead another cart that helps pushing the cart you're riding P:
And there is a little bug in the secret storage minecart in the room with the water column you have to dive up, the powered minecart don't push it and they get stucked in the room you can't enter without breaking any block.
I noticed that too. That really messed up my Let's Play.
