Hey there!! I think this comic has a lot of potential and it's a really interesting premise! I think you'll probably get more helpful critique if it had more pages but I'll say what I feel so far :>
story: there's not much to talk about plotwise for now but i think the world is interesting in a slightly silly way : 9 if you go the comedy/action-comedy route i will definitely be sticking around!! with this world it would be nice if you went for the light-hearted adventure time-ish tone with silly non-dangerous villains and low stakes conflict but that's just me : p
characters: i think the mc is very unique i really like how you didn't go for a typical look!! char design is pretty on point so i can't wait to see what other game inspired characters you come up with in the future
art: cute but doesn't seem very stable, but there's nothing much that i can feedback cuz it'll naturally get better if you practice a lot, jiayou!! the only thing standing out to me is the colors are a bit too saturated, but don't tone it down too much because i think it fits the world. adventure time level of color brightness would be great : D
also i like your pacing and dialogue, especially the last page. idk why but it really piqued my interest for some reason! good luck for your comic, keep workin on it!! it looks like it has a bright future hehe
