I like the visuals and audio. Its higher quality then I expect for a jam. But I had to restart 2 times because of bugs.
At first one, an enemy stuck inside me and follow me everywhere. When I move on single directin I managed to make same distance. But when I hit, it takes no damage. Enemy cant deal damage too but anmiation plays.
In second one, after killing the boss I entered the bottom-right door which leads to complete darkness(brown you used in game). There wasnt even character and nothing works so I had to restart again.
Also, not game breaking, but Jack can give infinite money.
(I understand that its hard to properly debug a complex game like this during game jam, but at least having a way of loading last checkpoint would be nice. Like holding down select.)
