Blue-Collar Astronaut is about piloting explosion-prone spacecraft for a living. It plays a bit like a modernized Lunar Lander if you could leave the moon and take on low income work. It plays out in glorious hand drawn 2D done by the talented Maki Naro.
I'm a huge fan of old school Atari games like Lunar Lander, Missile Command, and Asteroids. I think a lot of what made those games so successful (and why they continue to be successful) is how approachable they are. For instance, Lunar Lander just has 3 buttons - left/right buttons and a throttle (as is the case with Blue-Collar Astronaut). It doesn't take long to get a feel for controls like that.
These classics also coupled those intuitive controls with gameplay that progressively gets more challenging and entertaining. This is especially an area that Blue-Collar Astronaut focuses on. Expect surprises and twists on mechanics as you progress through to over 50 levels.
