This is the first one so far and I think it's one of my favorites main game levels.
And the new bullet type... I already hate it :D
Why? There are 2 main reasons why I find these bullets kinda questionable: first of all, solid-hitbox object that bounces from the wall at random angle have a potential of creating really messy or undodgable patterns. But it's not such a big deal if level maker uses them properly. The second and main reason is that there is no indicator telling how the bullets is going to act. You can't tell if it will bounce or if it will get destroyed after touching the wall.
This could be solved by adding some small indicator or extra graphical effect. Some kind of tray that bullets left behind them when they hadn't bounced yet. It would make predicting the patterns and trajectories much easier.
