Also, you’ve gotta make Wizorb and Ninja Senki for the iOS

Wizorb has most of it and Ninja Senki too, but why is there not enough satisfaction? You are on the right way, but missed a detail. The part that crushes the satisfaction is the factor “frustration”.

1. The player loses his progress and has to start over from a far away place. He has a longer way after he loses. The way to the goal will be longer and longer, the player is frustrated and lose motivation on the game.
2. The player know, that something work wrong and loses because something went wrong (bugs, etc.).

In the above part you are right. The modern gameindustrie makes it wrong to make a game tooooo easy. They don´t want to have the frustration in the game. But in old times the games are often too hard. The secret to make a game good, funny, challening, but not frustrating is to implement the parts above. There only a few games, that has both and the games that has both, are really good.

There are only a few games, that get this point. One of this games is VVVVVV. An C64 retro Remake. This game is highly challenging and even if you die over thousand times even on the easiest difficult, the game is not frustrating. Try it out.
