Thanks for your playing and suggestions. In fact, I want this game to support gamepad(I like gamepad operation personly). If you connect a handle to the computer, you will find that you can also move the character (although the operation feeling is not very good now). And for the operation, it also supports WASD for movement, and then L key to jump.Because this is the first game I submitted, I haven't finished it, and there are still many problems. I will try to let players can set their custom keys in next updates.
