I had lots of fun! It took me a while to understand that the Quota referred to points, not money, but other than that everything felt pretty intuitive to me. I also made maybe a half-dozen runs, so I'd say the game has good replayability.
The one improvement I'd suggest would be changing the keybinds or allowing the player to do so. With the current layout, I was essentially playing with only one hand, which got a bit tiring as the levels got harder. It would be nice to be able to move with WASD and do other actions/use skills with the right hand.
Great job!
