Cool concepts and I like the game so far but I reeeeally wish you hadn't picked the space bar, the button that is typically "jump" or "scroll through menu/dialogue" in other keyboard-based games, as the button for "monumentally mess up the level if pressed accidentally" in this one :/
In the Gravity Chamber section, why do I have to click on the door instead of the key? You can click on all the rest of the keys in the game to unlock things.
"If an enemy dies or is killed in a level with an artifact, you will not be able to gather or leave with that artifact."
I don't think you understand what the word "enemy" means.
Great game and cool idea! A few improvements, though:
The restart button is too close to the skip button, so I keep accidentally pressing skip
Also, if you press any button on the header (restart, mute, skip) then any key on the keyboard, those letters will be entered in the title of the button
Implement R to restart
Noted! I've added an option in the options menu to switch the key that discards your blueprint from SPACE to BACKSPACE. Hope that helps!
