This game is made by Anton Schillén, and I helped him with creating art assets. The game concept is a mix of the traditional mobile game Snake and the classic board game Alfapet (Based on the game Scrabble).
You play as a snake and you have to collect letters during this minigame. When you have crashed with the snake you have to make words by using the letters you have collected.
