I really like this game. It's a lot of fun, the concept is great, the music is a good fit, and the art style is appealing and evokes feelings of early console releases. The tumbleweeds are a great mechanic; I love that they can be helpful or a hazard depending on the context and how they happen to bounce. The game also feels really polished and well-made.
I wish the difficulty curve were less steep; it often feels like death is out of my hands due to the particular block patterns I get, even on the first level. Slowing down the speed at which the blocks fall in the earlier levels, and/or providing an indicator of where the next block will fall (which could give less warning and eventually none on later levels) would go a long way toward smoothing out the curve. My only other point of feedback is that I would have never found the super jump on my own, and it seems like that's an important tool for survival in this game. While a real arcade game might have physical artwork explaining the mechanics, we don't have that here, so I think a gameplay demo showing the feature or an attract-mode tutorial card would be a big help.
