Hello,
I am happy to announce that Spaceship Idle Playtest 2 is now available on Steam - simply download the free demo from Steam page to join the playtest.
The game has been rewritten completely, and here's a brief introduction to the new version:

This playtest has a simple tutorial for your first run - it should take less than an hour to complete. The whole playtest contains 6 ~ 8 hours of gameplay. If you have bug reports or suggestions, head over to our Discord Server (#spaceship-idle channels)
Finally, if you have joined the first playtest, the game should reset your old save. If you cannot launch the game, you can perform a manual reset by deleting the old save file: C:\\Users\\\\AppData\\Roaming\\SpaceshipIdleSaves\\\\SpaceshipIdle
