Glad to hear it! There's a second monster pack well underway, I've made 18 or so sprites so far - I may want to add some idle anims and attack/hurt frames to that one though, so there's still some work left to do on it.
Do you by chance have an idea of when this second pack might be available for purchase? I'm currently working on a game for my semester's final project using your assets and I am in need of some boss monsters for it still. I would like to keep the art style consistent if possible so I figured I would check with you first before I source them elsewhere.
