GamePatchNote Digest
Seeders Patch Notes — August 21, 2015
Aggregated from Steam, cross-tracked with Battle.net coverage on GamePatchNote.
The level editor is officially not supported yet.
It mostly works, but it is still not very user friendly and does not have complete documentation. However, you can try it out by pressing F7 in the main menu. You can then place player on the screen by pressing 4, and some enemies with other number keys. To toggle the background image, press T.
I plan to release a new version with more user-friendly and well documented level editor in the future and then I will mark that the game has a level editor.
