cool game. Right at the beginning of the game, after the capitain dialogue, instead of going down, I decided to go left (me no like rules), and after going to a screen with a boat, I kept going left, then idk but I think the game closed, the screen got black and I couldn't control anything (webgl version btw). Going right just make me loop in a screen.
In the actual cave with the gems, I noticed that the submarine kinda have an eye lol, pretty cool. Still in the cave, there is a section filled with blocks you can explode, and inside the blocks, there is a couple of gems. But if you leave this section, and come back, the explodable blocks and the gems respawn, what means MONEY FARMING TIME. I got the 128 gems (133 actualy but ok) really fast with that.
I decided to keep playing the game, then I noticed that all the screens respawn their explodable blocks and gems lol. After some time I got over 100 gems, and left the cave, followed the boat in the surface until the game closed, and selled all the gems I got underwater. I obviously got fired because I refused to do the mission, but now I have money enough to live a good life for a long time...
