Beautiful work! I loved the art, both the start menu and the cutscenes are amazing! The sound effects are also really good, Louise's voice is really cute.
Gameplay wise, this works well and it's pretty fun, at least for a time. The grapple is quite satisfactory and it's fun to jump among the circular saws in the first industrial levels... until it becomes too hardcore and tedious :D Once I finally reached the final level, I had the level freeze on me (gray screen), so I went to the source files to still be able to see the ending cutscene - which BTW didn't seem to show up, it looks like the animation was not autoplaying, but that might be due to me loading the scene directly instead of properly winning the game.
At first I felt that the rectangular and flat colored foreground was a bit too contrasting to the great cutscenes and nice character animation, but there's so much level design work for a 1 month jam game that I don't think you can be blamed for that :) And it avoids distraction with a busy foreground when the gameplay is so focused on precise timing.
