I thought this was a really cool idea with a lot of charm! The shopkeeper especially is a super fun character and design. However, the hit detection was questionable and that really made it difficult to interact with the bomb defusing stuff, which is the core of the gameplay really. I also found it too luck based on which bomb defusing squares would be the right ones versus the one that kills you. I think maybe some system of being able to logic out what's behind each cover would lead to more rewarding and puzzling gameplay.
