Thanks for the feedback. 👍🍻
The idea was not inspired by The Lost Vikings. Initially the idea was to change the abilities automatically when you get a gem, but I changed it in the last day of development to give the player the possibility of changing abilities accordingly to what he needs to get over an obstacle.
Regarding the in air control: it was intended to have a bad or maybe better said, reduced air control. This was inspired from old 8-bit and 16-bit games. 😁
