Fun game I completed all 5 levels!
The game play is simple and fun! It's easy to understand what to do while also be challenging from dodging enemies and collecting cards to get treasure/money.
The leader board and timer system is a great touch which adds replay-ability if you want to go for the top time.
The only thing I would change may be to decrease the map size. There were some areas that were open and didn't have enemies or anything. But this is just a minor thing overall good job!
