Thank you for the feedback!
So some of the collectible positioning was meant to be a minor bonus if you happened to use things like the wind inflation spell as a regular smart bomb. Meant to give you a little extra reward instead of only removing enemies. The currency will be balanced in a way to where you shouldn't have to worry about missing them as you can replay old sections to get more currency. I made sure that meaningful item unlocks won't just be randomly hiding in the treetops for example.
In regards to losing shards/power on death, I am going to add a system where if you fall off an edge, you will teleport back up, but it will have a max charge count and you'll get one charge every time you pick up a symbol.
In addition, I'll make it so that on easy mode you have infinite teleports and you just lose a small amount of health instead.
