Necktie Angel: Smite The Nazis Gameplay | Indie Meme Shooter | WTH Is This

How is this game suppose to let me fight the Fuhrer if every time I pick a meme up or I press 'E' the game ends..? I didn't expect much from the game but in this state is just unplayable. The dev definitely need to patch this.

From Steam:
" H****i Angel: Smite the Nazis is a 3rd person adventure game, playing as a beautiful anime girl. You were sent to spy on Nazi equipment and you found an unusual Nazi lager that is swarming with Nazis.

In the camp itself the Nazis hung posters with various memes (Hmm, this is probably a disguise), the camp is full of surprises (or maybe not), so the Soldier, be careful, oh yes, Hitler in disguise with memes is also hiding. You need to kill BOSS HITLER! And also destroy Nazi technology. Forward!

What awaits you in the game:
Enemies in the form of many evil Nazis
Beautiful anime girl with powerful weapons
Posters with different memes
Funny boss Hitler in memes
Easy game to relax
Ability to blow up Nazi equipment
Relax and neigh to funny music "
