First of all: Congratulations on your first own game! :) It's always awesome to finish a project (and especially your very first one) - congrats on that!
"Hi! :) Could it be that the browser version has a few bugs? I'm able to pick up the key at the beginning, but unfortunately, I can't use it anywhere. E/F/LMB don't seem to work, unfortunately. :( When I click on the screen with the mouse, the game sometimes crashes and I have to reload the browser.
Shame, I would have loved to play it to the end. Maybe you could upload a Windows version so we can get a better impression of the game? Best regards!
