UI is designed with a Game theme in context. To understand the UI better I recommend you read the game theme below
THEME: The player and his dog when subjected to an experiment were thrown into a new world where people
never saw colours. We are the only coloured ones and we need to escape/paint enemies to find an
optimal solution to live. So, we need to paint enemies to kill them and we need to escape from enemy water guns to live.
UI EXPLANATION: UI changes based on the colour selected by the player
The player's current customization is a flat red colour with maroon touch. So, whenever the player is
alive, the game UI is red in colour and whenever the player is dead, the game UI is black in colour.
Whenever the player is hit by water guns and loses more than 50% of health, the UI will have partial colours of red and black.
Besides that, dog is the companion of the player. There are some emotional moments between dog and player in the game. To extend that emotion beyond the gameplay, the exit screens are designed in such a way that the emotion must be felt for the gamer.
