I couldn't arrest bob for some reason so I kicked him to death. Now the boss took both my guns!
But seriously I couldn't figure out how to arrest. You should add the mouse needs to be over the suspect.
After I got past that the game was very fun. I got the basic squad controls down, but struggled with controlling individual squads. I think a better method would be tie each squad to a number key (1-9) then you need to hold that number while you select on the wheel. Just an idea. The wheel was a bit jittery or buggy to control, but I did see the option for it and didn't mess with it.
Spells were cool and fun, but could definitely use more. Scry, grease, fireball etc. I did enjoy dropping anvils on people though. Really I wanted more ways to approach the problem of closed door then "drop some anvils in, maybe throw a stun grenade, clear and hope for the best".
Overall love the concept, enjoyed the gameplay, and liked the humor/vibe.
