Skyline is a casual puzzle game in which players must spell words using a board of movable letter tiles. Players rearrange letters by swapping or exchanging positions of two letter tiles at a time. The game will feature different modes. First is an ascending challenge curve mode called Level Play. Level Play is structured with stages in which the player is given a set of rules and must create a certain number of words for that stage before time runs out. Endless Mode is more of a sandbox style play where the player is given a timer and a constant board of tiles. The only objective is to score as many points as possible and try to prevent the timer from reaching zero. Skyline provides depth with the introduction of different 'special' tile types that have effects or rules that add a unique twist to gameplay and player decisions. This, coupled with a score feedback system that rewards players for more efficient and advanced play, helps make Skyline an easy game to jump into and a fun game to master.
