I like the idea, but there's not much feedback on the interface. Most importantly, there's no sense of progress apart from the money counter, and since you use that to buy upgrades (which have no descriptions or names, nor any apparent effect when bought... unless you upgrade a LOT) the money counter isn't a very progressive thing. The New Year countdown at the top of the screen might be nicer if it was more graphical, like a bar stretching across the screen rather than just numbers.
It also feels like the squares get stuck on the rings too easily, just a little bit smaller hit area might make it feel more like you can actually have a close call and evade the foe just barely. At the start the squares move irritatingly slowly, and getting to the other side is more a factor of luck than timing. Maybe with slightly transparent upgrade buttons, a canvas resolution or warning colors at the bottom for the circles that will soon appear you could rely more on skill to time the openings instead of getting blocked at the last minute. It's a great idea, but I feel could use some polishing. Appreciate the medals btw.
Keep it going!
