I completed 13 levels and got stuck on the next one.
Overall, I really enjoyed the game! The ability to draw while moving is a really nice mechanic and makes the gameplay feel more creative and fun.
I got stuck on level 7 for a while, but later noticed that there's a hint available, which helped a lot.
In general, everything feels fun and interesting, although some parts might be a bit too difficult — or at least they feel that way until you get a better understanding of the physics and learn how to use them properly.
One small thing that bothered me was the "jumping" mechanic. Sometimes I had to move my mouse cursor outside the game window to pull back far enough for a full-power jump. But once the cursor was outside the window, it felt like I wasn't getting the maximum power (or maybe I was, but it just didn't feel that way). That was a little frustrating.
Maybe allowing players to start the jumping gesture from anywhere on the screen, regardless of the character's position, could help with this. Although it's also possible that this was just something I personally found uncomfortable.
Overall, I had a great time with the game! The drawing mechanic is really enjoyable, and despite a few frustrating moments, I found myself wanting to keep playing.
