This is a really solid game already. I like the tileset, the graphics, and the pacing. There's also some really good subtle mechanic teaching here, which is super impressive.
I do think I ran into a softlock, see the ending of my recording. Or maybe I'm a dumb ass. But the level did not reset to its original state (block not pushed) so there was no way to try anything else.
I wish I could interact with "Z" instead of "enter"
It may be a concession to the modern gamer, but a hint/solution button per level might help with overall player numbers.
