Love the look and feel of the environment. I found it difficult to time the jumps/shooting. But I loved that I could access the next levels to try them (even though i'm not great at playing games lol).
I think my only complaint is that I spawn facing sideways when the level starts. minor complaint, but after restarting the level about a hundred times (seriously bad at playing games), it got annoying to have to turn to start the level.
