Some platformers do have "W" keys for jumping. Honestly different players will have their own different keys on controls like someone wants "Z" key for jumping and arrows for movement. That's why long-term game development will add "Control Settings" for players to customize their key binds. If you don't like "W" key, you can try space key for jumping and arrow keys for movement. The game info already tells the controls. 3-day game jam is way too short to add control settings, and the game itself is too simple to add control settings, but I'm appreciated for you to enjoy the game. Rate it if you haven't, thanks.
