Looks like I overflowed your coin counter before I was able to beat the game! If that's not proof I had fun while playing, I don't know what is.
I love upgrade-based games like these! At a certain point, being capped to just being able to collect three rain/sparks per run made things a little slow, but still fun to play overall. Also, having the hippo face reacting to stuff was a nice touch, but it seemed to get in the way of my maneuvering sometimes. Lastly, the font made things hard to read. I kept reading "soales" instead of scales, and some of the upgrade descriptions were hard to understand.
Nice entry :)
