This proposal outlines a 2D metroidvania style platformer video game called "City Scramble" targeted towards teenagers and young adults aged 16-21. The game will feature enemies with different attacks and animations, as well as a boss battle. Inspired by Hollow Knight, it will include a title screen, character selection, and heads-up display to feel authentic. Research will be conducted on other platformers to inform aesthetic choices, music, sound effects, and gameplay mechanics. Progress will be evaluated by comparing the finished game to early experiments and research references.
