Pleasant, i had trouble where moving around also moved the viewport's scrollbars simultaneously but i have the same problem with Xuberance of Frozen Tetris unless it's fullscreen myself so i can't be hypocritical lol.
I'm either really good at maintaining balance on accident or maybe a little more volatility in getting way off balance would be serving the game to make it a little harder. One play through until dying though is only one data point.
Pretty happy with this one.
Gave you an itch follow, if you like what you see on my page consider doing the same.
