Really neat idea! I included it in my compilation video series for the Clicker Jam Spring, if you’d like to check it out. :)

Very nice idea. I think it could be improved by allowing for clicking on the arrows as well, rather than just having to use arrow keys

Damn it's good. But something even better to give more of a stepmania feel is... music! or at least have each key play some sort of music note when clicked so that it sounds like you're playing a rhythm game lol and also gives some sort of feedback that the player hit the key.

Its cool! Great theme idea and the graphics are good. All it needs is some sound and music.

FNF: The good version.

NICE!

Awesome entry! This is a very creative take on the theme and I love the combination of a directional game with an incremental game. 

This has great potential and with just some juice and polish (and some music) it would be an awesome game. I could also imagine this very well on mobile devices with swiping gestures. Great job!

Some improvement suggestions:

•  It would be wonderful to have a showcase of the items bought, like displaying the grandmas and clickers in cookie clicker
• Giving a wrong input should stop the combo
• It is not clear to me if the combo is just for points received by the arrow input or also for the input per second. 
• Some pumping music would really go a long way :)
