I had fun with this, it was too short! I like the premise, I think the character stealing mechanic is cool. Would definitely like to see some music for this and eventually sound effects. Some type of limiter on your dash/steal ability would be good too, it made things way too easy... for example, running from the boat, I just dashed the entire way, would pick up enemies, and then usually get hit by something and just pick up a new enemy to replace it, so it made that whole chase very easy. Other than that, it seems like the sprite and character actions were facing opposite direction? So i would be walking, but it looks like the box is facing left - which also affected the bomb-drop ally, as it would drop a bomb the direction of the face which would be the direction I'm not moving towards.
Overall a good premise and enjoyable time, I would like to see this fleshed out more!
