This game was definitely a challenge and very punishing. That being said, I disagree with Varii saying to drop this idea. I think it just needs some tweaks to give the player more control, like maybe a 3rd jump and probably more time between using your flame and dying. I liked the 'fling' mechanic personally, though I did find it to be somewhat unpolished. I definitely see what you're going for it just needs more tuning and probably won't be for everyone as it's skill based. The main thing is when the player dies it needs to feel like their fault and not the game's fault. Outside of that, the music was immersive, pixel art was decent. I liked the vibe of the overall theme. Keep up the good work!
note: there is a bug that happens when you switch between maps too fast that locks you in the entryway. I found that if you blindly jump and shoot your flame to die it will reset you back into the map.
