i definitely liked the look of the game, the environments are great and the the concept is neat.
the combat didn't feel good, it felt easy to avoid and cumbersome to attempt, the attacks the enemies were doing were unclear and attacking felt like i was putting myself in danger rather than getting rid of dangers-
the player was too floaty, the air control was poor, and the fall damage felt completely unneeded, sometimes i would take fall damage just from jumping through the small hilly spaces-if you wanted to do fall damage it would have ideally had a purpose (preventing you from going places or something to that effect)
as you say a better player controller would probbably be a good idea to attempt, i enjoyed the look and mood of the game much much more than the feel- the scaling of the environment was cool and the visual of when you first get on top of a giant's head and then you're controlling it was a fun moment, neat jam game :)
