Thank you for playing and for the feedback. I think you're right about the matchstick size and made it bigger. Also added a slight skew to the stick when picked up. There is a reset button at the bottom right corner of each level. I have it called out on the first level.
Ha! See? I had the feeling there was something like this, but I tried all keys and nothing happened. I also thought the characters shown in the bottom right menu could be pressed to invoke the action. I saw it now, but I kinda ignored/forgot it immediately the last time and never moved the mouse around to look for hidden menus. ;)
