Fair.
I've added some information to the game page, including controls and base mechanics. For the mode switching I doubt you'd want that text to be present any longer that it already is, considering how frequently the mode switching might happen. Thank you for the feedback on that, too late to fix now. Maybe later.
"...forces a permanent progression on the player..." Is feedback I don't entirely understand. You get a new weapon if its better than the one you already have equipped.
But yes, I did throw alot at the player at one time. Then again, the game happens over multiple runs with very low stakes. Consider it a learning experience.
