I think this game is very solid, from the idea to the execution everything is done atleast somwhat well.
The movement overall felt nice to play, especially the variable jump height was very fun to play with, but one major gripe is the double jump not having that variability, and always going max height, it threw me off quite a bit.
I loved that the game had different/multiple music tracks, it made the constant grind feel much less annoying/ monotonous, I just wished that there were a few sound effects because at times, it did feel a little empty.
The difficulty is very high mainly due to the randomness of alot of the attacks , that 2nd phase (yellow zone) was especially difficult, becuase of how unpredictable the buzzsaws were, in terms of when they fired.
I think that despite my complaints, the game is still a very fun arcade style game, that I could definitely see myself coming back to :)
