1st off thanks for giving our game a try and wow this is a long detailed review.
-yehp we wanted to make going to and from the shop a bit of a struggle, since the game pretty much revolves u trying to get back to it whenever u earned enough money, as for mushrooms they were originally more risky to use; hence why its not as important to take them... and we really wanted for players to figure it out themselves.
-will definitely need to polish jumping mechanics, wasnt supposed to be as hard as it is atm.
-wall jump bug, will fix
-were not too proud of the boss, will definitely need to fix alot of issues with it
