Aha yes! I too also fell through some ground thinking I'd land on something haha!! Definitely something we will be updating post-jam so it won't be so much of a 'WhoaOOaa I'm falling?!' reaction 
Ironically, I'm very bad at puzzle games too LOL (also because I'm bad at them HAHA)!! But I'm so honored that you gave us a shot and you enjoyed the drawing mechanic! c: Thank you for playing!!
