Nice! I love the theme and the sprite variety; the sharp edges on terrain are a little rough, but having more kinds of surfaces and obstacles adds a lot of welcome visual interest. (Also a little bit of difficulty, since it means parsing the board takes a little more care.)

I'm pleasantly surprised to learn I've gotten better at sokoban since I played it as a kid, haha. (Thanks, years of Nethack.) These are some nice levels--it took me a couple tries to see what I needed to do on level 8, and level 10 took me several tries to execute even once I saw it. The new mechanic starting on level 9 is more fun to play with than I would've expected if someone just described it to me.

Cool work, cute monkey. :)

Thanks for the detailed feedback!

And yeah I totally agree with the rough edges on terrain. I did this for a game jam and figured I'd have to cut a couple corners... At the end I had a little time left so I worked on smoothing them out a smidge on the later levels but it still ended up being a little difficult to visually parse. Lessons learned!

Also I had other ideas for cool mechanics that didn't make the cut. Maybe leaves room for a sequel. :)
