The ceremonious opening and ending made this experience really special and complete, I enjoyed the funny writing and presentation, the art style and characters have so much personality and they're all so distinct. Only thing that would have made the art better would be maybe adjusting the stretched-out 3D models that didn't quite fit with the hand-drawn look.
The games themselves each do something creative with the keyboard mechanic and make really good proof of concepts. I'd love to see this idea expanded on. I found the breakout and cherry games to be kind of tedious, I know that's how breakout is but that last block was so stressful compared to the other games, and I my keys were just demolished when I completed cherries but it was worth it.
