To everyone who is stuck on level one (and/or thinks level one is broken/impossible), it's doable. The problem is that the key mechanic of this game is non-obvious. I'm pretty sure I never would have figured it out at all without the hint from wellchan in the first conversation thread. If you need a clue, take a look at their post.
To the developer - while I appreciate a new mechanic in games like this, if the intent is for the player to discover the mechanic, you might have wanted to make it easier to run into accidentally, because I don't think it's easily guessable.
To anybody who needs to know the new core game mechanic, not just a hint, read on:
if you create an image of the player character using the blocks and environmental elements, that "avatar" becomes the character that you can move (with its own interactions with environmental objects and blocks.).
