Thanks for playing! Just to comment on some of the stuff you said:
the sound effects are WAY too loud compared to the music, the music was excellent and the sfx kinda ruined it 😭
Gotten tons of feedback on the volume of the SFX, i guess it is a bit too loud lol
make all the enemy bullets at least twice the size
Probably a good call, but since I suck at bullet hells, I decided to make them small so I could beat it to make sure it wasnt too hard xDD
when the enemies get hit, flash them white - don't make them transparent 😂 I want to SEE the hit.
The enemies becoming transparent is actually a bug lol, they're supposed to flash red.
the feedback on player hit is a little lacklustre too. I think it looks great, but I don't think it's very effective. A little camera shake, maybe some hitstop, that sort of thing.
I'll keep the screenshake in mind for my next game, I think that's a great idea!
really felt like I could keep going forever. Maybe increase spawn rate over time?
I was gonna add a higher spawn-rate over time, shorter shoot cooldowns, bigger bullets, etc, but ran out of time doing bug fixes :P
sometimes enemies spawned on top of me and hit me immediately. Not a fun time 😅 pure rng isn't great for this sort of thing! You want to be a little more tactical about it. If it were me, I'd spawn enemies in a circle around the player with a random angle and a radius that is random between two values, and wrap them to the other side of the screen. That way you'll never get enemies spawning on the player, and it'll feel completely random without being unfair!
I did add particles on where the enemies were gonna spawn to warn the player beforehand, but your idea is definitely something im gonna keep in mind for my future games :)
