Played a bit more runs.
The heavy chaser is super fun. The way it makes you dodge is great. The "fra" modifier is incredibly powerful. I like the idea of the absorver, but it is a difficulty enemy for something introduced so early. The ship takes a very long time to kill and creates a ton of little ships with ease. Also it bouncer all over the place so it is easy to get unpredictable behavior. I don't mean that it is a bad, just that its stats could be looked into.
While playing, I realized a custom mouse cursor could be welcome. At least for me, I lose track of the mouse position really easily. Each level has become much busier since everything creates bullets or ships.
Overall, the game is a lot tougher now. Maybe too much. I would love to know what is the maximum level other players reached, because now I cannot go further from level 25 and earlier levels were finished with single digit HP remaining. All of that while abusing FRA by the way.
