I couldn't really find anything that bad about this, but it was still wasn't that enjoyable. I think it might have been because it got hard fast. I think on the level before the one I wasn't able to beat, I literally had more than half of my ink left. The graphics looked kind of shoddy in this too. The sound effects weren't bad. I guess there should have been some music.
The only medal was one I did not know how to get, so it was hard to get motivated. I suggest you being a little more creative. You could have different kinds of obstacles. If you're a fan of these kinds of games, it shouldn't be too bad. It's just mediocre. I've played so many games that I have seen better.
