Before reporting bugs, ask yourself if the bug your seen might be intentional by the game dev, if so, don't post anything.

In the title, make a brief description of the bug like "Bullet traspassing certain enemies", not simply "Bug" or that kind

In the body, in the first line you should first put the version your playing (1.2.0) and next to it the platform your playing (Windows), for example: 1.2.0 Windows

The rest of the body you should explain how to make this bug. Images and videos help a lot.

Please be respectful, the post can be in Spanish and/or English
