Great game! Looks, plays and sounds great. It's challenging but feels fair because the enemies aren't too fast and you can kite them for a long time and also the hitboxes are forgiving.
Didn't try the gambling because I am not a gambling man but manager to get to 2nd place (at this moment) with 511 score.
My only minor suggestion is to maybe change the colour on the crosshair because it blends in with the enemies and sometimes it's hard to see.
