it seems to work well so far. I was really confused in the room where the men are right on top of you and it suddenly tells you to right click to grab. You might find a better way to introduce that mechanic. Other than that a health indicator would be really good. The canons worked well, though you might make the graphics for the bullets it shoots bigger so it looks more intimidating, or make the cannons look like turrets with smaller barrels instead. I appreciated the cover you left so I could make it pretty far into the game before I died the second time.
