I added it to my collections to complete someday. I think I just have to get used to wall jumping, which I didn't bother to put more time in it. The boss behavior seems basic enough for a first boss, I just had trouble when it goes at center shooting at left side constantly. The gap between the boss and the little platform above is small, I was worried I might get touch damage and my time is running out. I'll give this game a try someday later.
BTW, I forgot to tell. The game is well polished and seems ready for published. You might wanna release it as mobile game on Play Store, it works on my phone without issue.
