Nice concept, I like the style and the climbing mechanic. However, it's not clear what button is fire? Also there is a bug after GAME OVER I cannot restart properly, the cam look somewhere not at the player.
Nice, much better. Now it's clear how to move and shoot (s). After game over the scene reloads well! I would add that mechanic of shooting looks useless and could even leads to whorst situation than avoid shooting. Because of the level design (at least first two).
