I think the first quest should not be specific as to how you kill yourself.
I like this. My initial reasoning was that spikes killing players instantly is sometimes a frustrating gotcha, but that might be solvable through other means. Thinking about it a little harder I realize that the first quest might be the way it is because it was the fastest quest for me to test and it's the first one I implemented and just wanted some task I could repeat quickly which is not a good reason behind a design but is kinda a funny epiphany haha
Perhaps moving the hit box out (with an obvious marker) would make it feel better?
Good idea!
The bomb seed might be too powerful with the increased number of enemies. With the aura that takes 7 crystals instead of damage, I still had 40 crystals by the third camp (along with 8 hearts).
Hahaha yeah that could be. I've been having a lot of fun with the latest build because you sometimes get overpowered stuff like that happening, but it's definitely too much in some cases.
Really like your boss suggestions as well! Definitely one of the far less polished sections of the game so ideas for that stuff are really appreciated
