The opening was awesome. The art and shaders really impressed me. The animation of Lester and Isabelle are insanely good for a 3 week jam with Lester's movement and animations all feeling smooth and polished.
However, there is a rather large bug that soft blocks the game once you enter the van. The controls are disabled and you're infinitely stuck in the van. Also, small thing, but it could have used a pause menu and ability to exit the game.
Overall, the look and feel of what I could play was extremely impressive. I only wish I could have played the rest of the game.
