This is just a whole-ass game.
I didn't find the final fragment. But I did do the WIP rooms.
My general takeaway is that it's a damn solid Metroidvania, even in it's current state.
I really wanted to finish it, but a bunch of niggles wore me down.
My main issues:
-The map in it's current state isn't very helpful for mopping up towards the end. I was running in circles a lot trying to figure out what previous dead-end was now accessible, Plus those doors that just dump you in another room, instead of leading to an unexplored area didn't help
-It needed more shortcuts like the Seed tube connecting the Purple part to the... other part. Or fast travel or something. There's a few room insular shortcuts, but they weren't persistent, at least not for me.
-I failed to notice that those doors you need bombs to open needed bombs to open them, since they looked exactly like the gates that needed keys, so I left immediately.
-I'm a big fan of narrowing the field as the remaining collectables dwindle. Less things to find, in a large space you've already scoured. Like in inFamous, when you get to the last dozen or so blast shards, it'll start letting you know where they are. I guess, at least a general indication of which biome the final shard was in would have been nice.
-Maybe the check-points are a bit stingy.
-Using a controller and the analogue stick, I accidentally transformed into the Seed form a bunch of times when I didn't mean to.
That's all I can think of right now.
Still a great game.
Here are the recordings I have up so far:

Still a few to go at some point.
