This is poorly executed for several main points.
1: The game looks ugly, for a game that is meant to be played over a long period of time this is a major flaw, the presentation is horrible and there is nothing appealing to look at.
2: The game's "autosave feature" causes the game to freeze when it saves, in other words every 30 seconds the game freezes for a second or so, this gets irritating very fast especially for a game where you are meant to click a lot.
3: The entire premise behind the game is flawed, playing Pong is not the easiest thing to play, it does not automatically lead into playing snake which does not automatically lead into playing space invaders which does not automatically lead into playing asteroids which does not automatically lead into playing pacman. This trend continues.
For a moment here let's mention these choices of games, mainly pacman, pacman is an exceptionally difficult game that requires a lot of skill to pass by the first few levels. So how the hell would pacman be one of the easiest games on this?
No "skill in gaming" is not what this is about, this game is about how NEW a game is, not how hard it is. Which destroys the whole point of the foundation of improving your skill with games being the main thing to improve with clicks! If you can't get what you are CLICKING correct in a CLICKING game then the game is pointless.
