Thank you for your comment! You can shoot after you get a weapon. But first you must jump down from the hole on the right.
hmm I did manage to get the weapon and return to shoot the light bulb, but still nothing happens when I press "c", anyway is still impressive this was done in 24 hours :)
Sorry for the inconvenience. Something with the html5 version seems off. Please refer to my last devlog. Thank you.
