Thanks for playing my game and your feedback. I added gifs with instructions on the game page but I'll add a short summary here as well.

• Drag dice to the abilities to use them and find submarines.
• Tiles will say if they contain a submarine, or how many of the neighbours do (like minesweeper-game)
• By using the "Ping" ability on empty tiles and the "Depth Charge" ability on the submarine square you will get a smaller dice back. Really useful to make 4 dice last many tiles.
• When all the dices have shrunk to crappy 1:s, spend a reroll in order to access the better abilities again before being forced to "End Turn" to get more dice.
