The bad - No sound, can get upgrades cheaper by walking away from and back again to shop, speech bubble would be better if it disappeared when walk away, the carrot digits only allow 4 digits so 10/160 looks like 10/16
The good - Love how you got something to collect while jumping through the gaps, artwork is top notch, I like the inclusion of upgrades, the way the carrots come towards you looks cool, the animation going down the ladder looks awesome, the different speeds of the rats is a good thing and the general attention to details is really nice
