Thank you for your honest review! I don't think that the limitation of the mechanic is the core problem, but the lack of time to balance the numbers right and to develop a greater variety of meaningful items to buy. Initially there was a loot system planned and the shop keepers would have received new items as the game progressed, but due to time constraints these had to be cut. I hope you had some fun nonetheless! :) If you like the style of our artist, stay tuned! We're already planning our next project and will be sure to take the time to balance it right and find ways to make the gameplay more engaging!
