Simple and simply delivered. Perfect for casual strategic gaming. I can easily tune the game I wish: mostly I seek something like "relaxing but not boring". The bigger maps on the higher difficulty settings could present I decent challenge. It is the sort of game that I am always binging back, so very high replayability value.
I play it now and then when I feel the need to relax for some minutes and stop worrying about something. This is the sort of game that totally absorbs me. Its tactics element, by choosing how improve your ships, adds lots of depth. Definitely does not feel like a still in development game. I'm following the constant updates from the developer and I'm curious to see what will it be when finished.
I've spent a few relaxing hours with this game. Most of the puzzles are quite simple, taking more patience than skill to solve them. The art could be amazing if taking advantage of higher resolution screens. So if you want something relaxing and not much challenging though somehow engaging, I do recommend it.
