That's one of the biggest feedback we've gotten, even though we have controls tab on main menu to show buttons :D Numbers 1-2 are for switching between equippable items. The game can be completed without those, though!
Thanks for playing and making the video! It's a shame how unintuitive the flashlight and fireaxe usage is, might have to fix that.. :D Might also yoink that Left 4 Dead helicopter scene...
