I threw this together as a way to place in more symbols, as the style of game means that rather than a level ending when it is cleared the level continues until the player loses all their lives. As the player progresses the game moves faster. Basically the player controls the ‘spaceship’ which holds a symbol, and the player must drive the spaceship into the corresponding kanji. If connecting with the right kanji, the symbol changes to a new one (as shown bottom right) and the player searcher for the new kanji.
I considered as well the use of colour, and whether it’s necessary: will people connect the colour to the kanji too much? I figured there could be a ‘grayscale mode’ for people to attempt after beating a level if they want to improve their skills or for achievements or whatever.
