This is obviously a a benchmark for a GBStudio game as was Deadeus! Fantastic art! Fantastic Story so far. Fantastic Cutscenes! Really gripping "Hook" being the severed limbs. 

My only grips are the deceleration and acceleration are a lil slow. Makes it feel sluggish (If this is intentional then thats all good, I guess I just dont like that style of platformer). The well area when yours arms are cut off is very long and the areas look all the same I found myself getting bored/ lost during it

My main Concerns will be. What will combat be like? will it be fun and interesting or will it be a bit repetitive?  Can you actually pull of interesting swappable limbs that go with gameplay well? 

regardless this was really great! I wasnt even looking into paying much attention but the story did grip me pretty well immediately :) Looking forward to the full release
