KEYS

KEYS is a Metroidvania game demo where you need to collect letters to unlock keys, explore the map, and collect notes and the ultimate reward. Currently, there are only 15 letters in the game. The game can only be played with a keyboard. The demo features a save function; if you need to clear the save data, press and hold the 0 key on the title screen. The full version is expected to be released in about a year.
