This is one of my favourites so far, I thought it would be better if you had to move to the shop square so when you think you have enough money, you have to work your way through and onslaught of bullets. Also, I get that not being safe in the shop is a part of the intended experience but, I think if it's safe, it would be like a pause button that the player has to work towards. You know how near the end of tense boss fights, players sometimes pause the game to collect themselves, well it would be like that but the player has to put effort into it.
So yeah, I really like this one, great job
