I played it for a while! I think it's been mentioned below, but there's a point where the game gets as hard as it's going to get and it's pretty early on. That said, I pushed around, I liked seeing the buildings become transparent as you pass behind them!
The pixel art is really well done, lots of nice effects with limited colors and some nice dithering transitions for gradients, I really like the nice touch of using the same page background color as the Game Over screen's darkest purple, it looks really good!
Very solid game, just needs more on top of the foundation you've set up!
