Darwinia

A short but sweet game action-oriented RTS that allows you to play it on your own pace, either enjoying the audiovisual experience and the story or blazing through stuff once you know what you can do.

I really like challenging gameplay and situations, but the last 4 levels are pretty insane and you will have to restart them a lot to know what to do, especially because of those flying enemies, which are just almost impossible to hit with most the units you have.

People often talk about timeless design and this is definitely a game with one; the graphics were simple and blocky even almost 20 years ago but the retro visuals look still great and the game itself runs great even on modern PCs thanks to developer support.

The SFX and soundtrack match the atmosphere with quirky noises and some great chiptune and tracker music.

In either case, the learning curve is pretty fair to get you reacting fast enough to know how to push yourself to completing objectives in each of the world's zones.

The game does have a well-executed Linux port, which I very much appreciate.
