After a neutral ending with half the slimes alive, decided to restart and save them all.
The mechanics of pulling the slimes is different from most of similar games. And open some room for strategy, like the one I use on my second run to save them all. Never used the push option (I did it just for testing, but didn't found it useful).
Sfx are fine, a little loud sometimes, but ok. Didn't found other major issue. The game is fun to play, and there's room for more levels and maybe other mechanics.
Nice job! Congratulations!
