But I think is too hard, and at first I think we could move down but we can't, that make a big confusion for me, also I don't know where is the theme color :/
The concept is pretty cool, but I think the is a bit wasted that the differents color inks do exactly the same thing, may need more time to do work with that
A simple concept works, but may need more variety for gameplay, I recommend you could make the different color more visible at the begining and becomes less and less clear
but the control isn't confortable, must improve the direction of movement and make the zone detection of trigger bigger, also I recomment change a font, for now it's hard to recognize.
The "you are your own enemy" limitation is relate to the power you collect will affect the difficulty of boss, for now the feedback of this part is missing :/
