Some thoughts:
- Clicking anywhere in the window counts as hitting the red button, which means you can't navigate back to the main menu using the on-screen buttons.
- Your ship shakes whenever you press the button in Shooter (and even moreso when you hold it), which can throw off what direction you're going in and get the ship stuck on the sides of the screen.
- Cave and Hurdle Jump should just be part of Platformer.
- Mini Golf is my favorite game in the collection (next to Pong), but I wish you could press the red button to skip to another hole when it's obvious that you've missed a shot.
- I think both of the golf games could use pixels to bound off the edges of the shot meter, just to make it easier to gauge when you've charged your shot all the way.
- Flappy's sound effect plays over itself almost constantly.
