A very very well designed puzzle game! Great job!! i love puzzle games but I'm terrified of actually making one because designing the puzzles seems difficult to do well to keep the right difficulty of the game and you did it perfectly! You also incorporated the theme pretty well too imo because I was often scared of the slimes until I fed them and then became best friends haha. one bit of advice is maybe a bit more variation on the objects in the levels? the slimes themselves were perfect with the colouring to know exactly what they did after you learnt but I found that in some levels the boxes and the door were kinda hard to spot as they looked very very similar to the rest of the level, perhaps that was intentional? but in most cases it didn't feel like it was. that's all of my notes though well done!!
