The Binding Of Isaac

Dead Cells

Terraria

Cassette Beasts if you like monster collecting type of games (in the spirit of Pokémon). Should be below $20.

Currently playing through it, although on Steam version. Awesome music and well done pixel art aesthetic.

Unpacking maybe fun

Stardew Valley.

Hades is pretty fun and comes in under that budget.

Just bought Escape form Ever After.

It's turn based. Rpg. Looks like paper Mario. Apparently it has anti capitalist humor story. I literally just started it today. But has great reviews.

A similar looking game and game play is Plucky Squire. Haven't played it but plan to.

I also played Bloomtown a while back. Quite liked it. Turn based rpg. Pixel art. Decent story.

Also liked Sea of Stars. Dlc was really fun too.

Moonwalker 2. I have the first on steam. It's a farming dungeon game. Cute graphics. Second one, (so I've heard) is improved version.

Other game I played

Moonstone island. I quite liked it at first. But progressing more at the 3/4 point is too much of a grind.

I got on a pixel RPG kick for a while so that's why a few of these are similar looking.

All beautiful games.
