Version 0.1.5 for the pre-alpha has released! Patch notes here:

THIS IS A VERY SMALL UPDATE

- Slight improvement to the performance of the game

- Changed the "Quit" button on the death screen to now go back to the main menu instead of quitting the game completely

- In 0.1, the "Medium" and "High" graphics settings were just the exact same graphic settings (which was High) but that has now been fixed and the "Medium" graphics will actually display medium graphics. (check screenshots to see the visual difference)
