Teddy Floppy Ears - The Race is so close to being a borderline hidden gem and is easily one of the most polished-looking games that have appeared on this series. The controls and counterintuitive physics significantly impact enjoyment, while the difficulty level (even on easy) makes it likely too difficult for a young child. It's full-price is $4.99 and at that price point, there are other options available -- especially if you have consoles as an option. For a 49c kart racer on Steam, it's actually quite good. (High Borderline)
Accel Magician Mimi is a really short single player, 2p co-op, or 2p vs horizontal shooter with fantasy creatures and a mage girl instead of ships. The engine to be used in 12 games offered by this company to create the identical game with new assets, but this game, as a standalone product, isn't all that bad. It's way too short, though. Only pick up if on sale for 99c or less. I spent 59c here and don't regret the purchase. (Low recommend)
Order no. 227 is a Connect 2 game template reskinned, with poor hit detection, controls that often don't work, broken checkpoints, and everything else you'd expect in a Steam shovelware low effort asset-reliant / asset flip title. Even at 49c and already having friends who own a copy who are willing to play, this game isn't worth the price of admission. (Avoid - Abandonware / Asset flip)
