Pretty fun, this reminds me of those old flash games like Learn to Fly where you try to go as far (or in this case, as deep) as you can. The sound effect that plays when the potato is shot out is pretty funny, and it was also funny how the potato got mashed up if it collided with a wall. I think adding some upgrades or other goal to each level would make them more fulfilling (e.g. could have a level where the goal is to get 100 deep, and upgrades help you dive deeper). Otherwise, very fun game and fun time with this one!
