I liked the game but it crashed on me unfortunately (I was on a stage with 4 pillars). and it's pretty difficult to get rid of the enemies without getting hit because the warrior constantly moves forward and collides with them. an interesting idea nonetheless! I didn't see through the whole prototype but if you are to continue development, I suggest coming up with something a bit more crucial to do for the warrior. maybe you could try mixing up the dimensions in some new ways? that also can be very interesting.
and I like the thumbnail a lot, making a whole game in this style would certainly take it a step further.
TLDR keep up the good work! :)
