A well polished and engaging game, the smoothness of the animation, both the characters & objects, and the level is very visually impressive and appealing. The leaderboard was something I wasn't expecting, but was appreciated and a good addition. Not many people would think that a leaderboard would be something that they should put in, but they would be surprised at how much something like that increases longevity and engagement. Really well done.
I do feel like the smoothness of the level has a small downside where it could potentially be slightly nauseous at faster speeds. I personally didn't experience anything, but I couldn't get scores more than 1000 so I couldn't be certain on that. Some audio and polish here and there would improve the user experience but a notable degree. Finally, consider how people actually download and play the game, is this the most efficient and user friendly method that you could've done?
Overall, I don't have much to complain about. This is a really well made piece of work which is a very strong start this early on in the year. Keep this attention to detail and quality up!
