For the final image of the upgrade shop I decided to remove the planks of wood boarding up the front because it gave off an abandoned shop feeling which I felt oppose the idea of trying to attract potential businesses, instead I gave it a freshly built stall look to hopefully make it more attractive.
For the obstacles I stuck with my designs previously and just tidied up the images
For my HUD I stuck with the simple design to not distract the player during gameplay, although I did add a place for the menu button incase players what to pause or quit the current game.
In the end I decided against making a traditional boxart in favor of a app icon due to my game idea drifting more into the mobile and app side of things.
