Blue Fish Goes Treasure Hunting

This is my first attempt of making a game using the Godot Engine. Comments are appreciated.

In this game you are a fish, who wants to search for some treasure chests! Collect air bubbles to gather air supply - you can shoot enemy fish with bubble bullets. Avoid or destroy mines. You can also lure enemy fish to crash on them. 

Collect all treasure to gain access to the lair of Boss Fish! Slay it to grab the final treasure and win the game!

Controls: arrow keys to move, space to shoot, escape to return to title screen.

Features:

Randomly generated layout each time! You can choose the map size from 4x4 to 20x20

Powerups: hearts will replenish your health, shields will grant you invulnerability for a short time, speed boost - self explanatory, zoom out - the camera zooms out, so you can have a broader view, compass - will guide you to the nearest treasure.

The game is still under development, so there may be (or rather surely are) bugs :) Doesn't work under Internet Explorer and older versions of Edge. Not tested on Safari.
