I feel really stupid but I can't understand for the life of me what I'm supposed to be doing on the first level (cake). I'm sure I'm missing something obvious but as far as I can tell I've tried moving both the chef and the tiger into every single possible square.
edit: Oh I figured it out, confirmed I am indeed just really stupid haha! I tried merging them back together first thing, but I figured crossing paths would be good enough for them to collide, I didn't realize they'd need to end up in exactly the same square.
I think a tutorial would definitely help a lot, although many of the rest of the mechanics were more self-evident after I figured out the first step (although I haven't completed the latter levels yet). Seconding also that the keyboard was an issue. I don't have my keyboard set to qwerty by default and it took me a minute to sort everything out.
Other than the difficulty curve and want for a tutorial, the game feels really well-made. I'm giving you bonus points for your backwards dev diary in discord as well, because that was just brilliant!
