nice!
on my first try, i jumped up and left and fell all the way down, and could run underneath the level, and was curious to see if that was intended or not, but it didn't seem to be. pressing escape to bring up the menu and clicking the play button respawned me to a new starting location. and so i could play a bit, and loved the combining elements! after a short while, though, opening the menu again and pressing the play button now shows the credits screen, as if the two top buttons triggered the same thing. i can no longer go back into the game without refreshing the page. on another run, i tested it again and, indeed, for me at least, escape button - click play button does change the slime's location, and doing it a second time ends up in that credits screen dead-end.
with that said, the game is beautiful, and the sounds and music fit really well with the style! very impressive project for a jam!
