Thank you for playing our game. WTBasil did an amazing job on the graphics, it’s worth following her, if you hadn’t already. I’m sorry you had problems with the controls. I thought WASD or arrow keys for movement and Q/E/SPACE/Enter for switching the shells is the most intuitive I could do, or you maybe have another problem. Try playing the desktop version, it supports gamepad, unlike the browser version. Also try to directly look at a shell you want to switch. Maybe that helps.
