Recommendation: Ducksoup Dungeon
Let's jump right into Ducksoup Dungeon. It's a free web browser playable rogue-lite on Itch.io by developer Richard Lems, also known as Blastmode Games. You might have heard of Lems' work on the game Mighty Goose. In the game I'm discussing here, Ducksoup Dungeon, you choose one of four heroes. It is playable in a web browser or can be downloaded. Starting with "Slashchicken," the first hero is a chicken. With amazing firepower at your side, you'll blast your way through and collect coins. Each play's collection can be used to unlock the other three heroes. Every level features hidden procedurally generated areas, meaning it can be a different layout every time you play. The levels, of which there seems to be an infinite number, are filled with containers destructible for coins, reached by eliminating various mobs.
