How do you get he Die Hard in-game achievement?
Such a great game! Wish there was more like this. :) 10/10, only thing I would change is how long the game is (by making it lightly longer) and I would give it a few more upgrades, for example as p0x0rz said, a rope or ladder upgrade. :)
I think it would be quite good to have a levelling up system for this game. Also, more upgrades and weapons might make the game a bit longer. But anyway, it's a great game! :)
