Thanks for checking it out!
Yeah, all the collector upgrades let you turn an obstacle in the game into a collectible one, two, or three times in a run. That was my core design concept . In most games like this, it's about avoiding/defeating enemies and collecting power-ups, so what if you had the power to turn the enemies into collectibles? The mechanic ended up playing out in such a way that the collectibles ended up acting as pseudo-health, but I really liked the idea of still needing to avoid early enemies so you could save the 'hit' for harder sections. I really want to expand upon that idea in a game with more time.
Anyway, I was hoping that the player would jump from the text saying "you can catch dragons for their scales" to "collect dragon fire" and understand that everything could be a collectible. Being more explicit for a jam game should have been a priority though!
