I picked it up on sale and it was worth that price (50% off). Multiplayer seems to be non-existent being such a niche game, so you're left doing missions and skirmishes against the AI. That is good, except for the fact the game features a ranking system for progression, and you can only progress against human players in multiplayer. You can't make a two-player multiplayer match with just yourself and the AI either, so if there's no-one else in multiplayer, and if you don't have friends to play this with, the game ultimately ends up feeling quite limited.
The graphics are minimal but nice, and add to the ambience provided by the atmospheric music. It has a nice parallax effect, scanlines going across the screen and flashes of text in the background, making the whole game play like you're actually at a command screen directing portions of an army.
As mentioned, the music is very atmospheric. It's space ambience, and some of the tracks are decent, but some tracks are apparent in their oddity. There was one particular track with what was meant to have a space opera singing in portions, but it was so gravelly in deep sections and so scratchy in high sections that it made me want to mute it, to be honest. The rest of the tracks are passable.
Gameplay mechanics are simple to grasp and the game very much plays like a real-time version of Chess. You have Battle fleets which are for space battles, Siege fleets which are for bombarding systems, and Invasion fleets to invade and capture systems. The latter two ships aren't too good at space combat, so it comes down to you to work out a strategy to balance your army out, as your fleet size is limited to the amount of systems you control. Balance is key, else you'll find yourself struggling for a little before either coming back to a level playing field against the AI, or losing gradually enough to not realise until its too late.
AI in the game is alright. I highly recommend learning the game using the Easy difficulty, as Trivial AI are almost completely stationary the entire match except for sending out Invasion fleets in a vane attempt to grab any sort of resource to build from.
Considering this is an indie game, for what it is the price is still a bit too high. A max of $10 with a decent community behind it would make this a lot more appealing to a wider audience, but as it stands is a niche game that will remain in its niche, alone, with no community to populate the core drive of the game; multiplayer.
