Core addition: captain can stock up to 1000-1500 coins in core and use a teleport to a random clear (watered) point on the map. For a minute main ship wont be shown on enemies' radars. Teleport costs up to 500-750 coins (after that all coins come to captain) and wastes 25% of core hp. Optionally make an animation of specific whirlpool under ship which lasts some time (e.g. 5 seconds). During this time ship can be hit with weapons or ramming and after that loses some hp of all blocks and weapons
