No, no no. :(
Kill the cat, drag and use it as weapon over and over again... When cats pukes and big crazy cats come and damage the wall. I just came somewhere to lvl 3 when they came (over 10) cats and raped the wall. Click here, click there. Click the corpses..
I can recommend better controls tat would be much easier;
Spacebar to shoot
Mouse to aim/upgrade/pick corpses
Select weapon can be still what it was.
But here's the point;
Funny idea but the gamplay is a fail. belive that.
