I definitely want a longer version! The way you can send blocks to the other player is brilliant, i wish you expanded a bit on that mechanic bc it was really clever. That said, the graphics look nice, the controls are fine but sometimes there are some issues with the jump. it doesn't always act when i tell it too, there's either a delay with the input or with the ground detection. Also, why can't we jump on the blocks? It's weird to see the character in the falling animation while standing on them. The music has a nice atmosphere to it, the text is clear and legible, and overall it's a nice premise to a cool platformer. Keep working on it!
