Strongly recommending the game #HighFleet.
I usually hate anything resembling a "bullet hell" game and sidescrollers aren't usually my preference, but this game is so singular and unique it needs to be experienced.
The premise is that you're in charge of a small fleet of gargantuan black-smoke-belching rocket-powered mountains of machines to run a guerilla war against a far superior force.
The graphics and sound design are superb, but the game itself is a masterclass on proper scoping. Everything that's included plays a vital part in making the game what it is and there's nothing extraneous.
The game is two-layer, much like XCOM. Half of it is frenetic dogfights between these massive rocket ships and the other half is a very challenging strategy/story layer about building your resistance.
Anyway, if you're a #gamedev and you want to see an example of an indie game done right, don't sleep on this one.
@LouisIngenthron that gets downloaded tonite. Looks gorgeous.
