I think you're being too hard on yourself in the description haha, this is a really great game for a one-week game jam and an awesome prototype to build on for the future! I like the sprite art and controls, I know you said it is too similar to Binding of Isaac but I actually prefer the shooting in this one instead since Isaac only lets you shoot in eight directions. The controls in this feel great, and I like the idea of switching between party members to access different shooting styles, while also having the AI control the other character to do some light supplementary damage. I hope you continue to build off this! Great game!
