Pretty good overall, i like the hand drawn artstyle, it's really charming and i like the "dog" 's design XD
i also like the fact that you can combine any amount of magic orb to generate a seemingly infinite combination of slimes and with a name too !
Tiny issues though, the turret enemies, they seem to have a real OP range and blast radius to their attack, but one thing i do like about them is that their attack also affect the environement, that's a nice touch.
Other than that it's a neat little game, congrats :)
