Thank you for your reply.
Using command prompt, it works. But when I double click, nothing happens. I don't get it.
Other indie games, such as Locomalito games, work fine. I only get this issue with your games.
I fixed it.
On Windows 10, when an exe was from an unknown editor, the OS asked you if you wanted to launch it anyway. Here, it cancels the launch of the game without saying anything, you have to right click and go into properties to unlock the exe (checking the very last box on the first page, I didn't notice the new option at first).
