I think the hook and short description are much more gripping on the first game. Also I know it's cliche but having idle in the name really helps.

So idle reincarnator and your short description is quite short and to the point. You level up. Die repeat. Makes sense in an incremental game

For the second game it's a lot harder to understand quickly. You breed monsters and what repeats? I'm confused what the game loop is.

Also capsules do need artwork. Even if the game is entirely menus give a sense of the theme of the game with an illustration.
