A bullet hell game with platformer RPG elements in between challenging mini-bullet-hell-encounters.
Featuring:

20 unique bullet-hell boss fights
A pretty alright story
A lever with an attitude

I can beat this in under 30 minutes, but every later fight needs to be puzzled out, I reckon there's more than an hour of gameplay here. There's no save feature unfortunately, so be aware!
X M
Interact with NPCs and reveal the lore behind this broken kingdom you apparently rule.
Z N
Jump & start combat encounters

In combat touch the red wall of the arena to damage the opponent
If a particular encounter is giving you trouble, you can enable 'drain mode' from the options menu. This will slowly drain the opponent's HP rather damaging them with attacks, think of it like an 'easy mode'
I made this game over about a month and a half; I wanted to make something kinda Undertaley, I don't know how much I succeeded, but I like this! I hit the cart size limit, which surprised me, but luckily I had most of what I wanted in the game.
@hahhah42 set up a speedrunning leaderboard!? That's pretty cool! Here it is for anyone interested
