Nice game. Is there a template for these games btw? I remember playing Dandy Cave Explorer that uses the same wood platform and also the coins and the main hero's design.
The game is very fun. I really like the design and the sounds. The upgrades are innovative and fit the theme perfectly. However there is no goal here. Even if you had not time to finish (or fully polish) it you could have just added a counter with an end game "you won" after 5000 souls or something. Or maybe an option to press escape once we had enough :)
