I found this game while looking for possible projects. I think it has potential as a TAS. The main character moves somewhat fast, the boss hit box is very lenient, you can take a lot of damage before dying, and taking damage doesn't slow the character down at all when running.
There is a possible disadvantage in taking damage at some point: it disables your jump for a while (although you can hit the jump button at the right frame to extend your bounce).
The first 2 levels are pretty linear, but I'm pretty sure the levels get more complex later.
You have to collect 3 feather thingies in each level before it allows you to go to the boss.
I completed up to the second boss in a short test. Obviously it's not going to be perfectly optimal first time around. I didn't take time to find the boss hp RAM value, so I'm not sure if just rapid firing against him is the best approach.
Anyway here's the first run through test WIP up to the second boss:
