Thank you for your playing. I'm very happy that you can enjoy our game. We want to create an experience like Doom (you can also see from the name of the game), so we decided to let you control what weapons you use.
We have noticed the bug you said, but we don't have enough time to fix it.(sad) As for "it only let you shoot when I was flat on the ground", our code's judgment on whether the dice is upward is too strict, so once the dice is a bit slanting, it will be judged that it is rolling. When you are rolling, the program can't know which weapon you are using, so you can't shoot at this time.
We will continue to improve our game. But until Mark releases the summary of game jam, we cannot modify the uploaded version.
Finally, thank you again for your playing.
