The game doesn't work for me. I can move and dash but when I hit a chest, I fire a weapon that then disappears.
Also, which button is "Start"?!?
1. I can't reproduce the bug you reported. If you have a controller connected try disconnecting it if you want to play with the keyboard instead.
2. ("Start") is displayed if the game detects a controller connected to your PC, otherwise the restart button is ("R").
Thanks for the feedback
