Alright. let me see... now it's a little more than i can handle, but I think I got the point.
about the death sound, I'll try to remove the death sound when you resurrect.
someone liked the 5th boss, some says they were harsh, and some hated them... that's.. a controversy..hmmm.. amd almost everyone says the final boss needs less HP. get that.
Here's my idea then, I'll make a new pattern using the blue wisp(fire thing) sprite in 5th boss, and the old one will go to extra chamber.
And for Final boss, I'll consider nerfing his HP to 450(no less), 100 for first phase and 150 for second, 200 for third. instead, it will become harder. you need to choose both or neither. OK?
and for extra chamber, no nerfs. no easier attacks, no lower HP. you'll need to suffer a lot to clear them.
It's optional and you don't need to clear them. just beating the final boss and seeing the ending means you cleared this game.
For the 5th boss, one thing you may consider is keeping the fireball the way it is now, but maybe allow player to be able to shoot it a few times to kill it? Also people on twitch TV were commenting that the voice over during the fight was a little annoying.
My criticism of final boss is not just me but from viewers who watched me play. People get bored of watching the same attack for so long, once you know how to dodge it, it just seems pointless to have it go for so long.
Also I am really glad I picked autofire in the start of the game because of how much HP all the bosses have. Could you imagine playing the game against bosses that have 100 HP x 3 (ghosts) or final boss that has 600 HP, then die and have to mash button that many times? Your hand would fall off. lol
Do not get upset about negative feedback, and yes it is your game. My stream tends to draw sizable viewers so reaction is not just based on what I think, but what they are telling me while they watch.
