Thank you so much for playing my game and giving your feedback! <3
I'm not too sure that I get what exactly you mean by constantly switching between keyboard and mouse^^" The only thing you need the mouse for is the start button everything else can be done with your keyboard. In fact I only realized that you can split/join and switch with LMB and RMB through your comment so thank you for that! =D
But I will give the controls some more thoughts and update them after the jam =)
