The slime character designs are adorable and the "How To Play" screen explained the match-3-to-pop mechanic clearly before I even started. I liked that colliding with slimes actually hurts you, which forces real positioning decisions. My run ended very fast (lost all 3 hearts within seconds of wave 1 starting) — a slightly gentler ramp at the very start of wave 1 would give new players more room to learn the aiming before the pressure ramps up.
