Yes you're right, I should a bit better explain how to play it, but this was my first game jam and I worked on it almost the entire weekend so I decided to finish it like this and finally relax a bit. I really enjoyed this game jam and I sure I will participate in the future in other jams as well. Also I'm really looking forward to the next wowie jam. Thank you very much for this amazing jam;-)
Ps: You don't have to place objects anymore, just hit play.
