Shield obstructs the view considerably. The moving blocks don't look any different from the regular blocks. Some of the gaps are too small. Your low velocity is annoying at the start for jumps.
Later on the hitboxes are clearly badly tuned because I'm hitting things that I'm clearing with jumps every time.
Also music not slowing down when you pick up a slow object killed the atmosphere.
Also the view angle is terrible.
My top score was 67. I felt like that was probably good given that the difficulty is so badly tuned. Almost immediately having to react instantly to the next obstacle after each action is such bad design it should have been glaringly obvious to you before you launched this.
re: author's response. this isn't about making the game difficult. it's about the crappy lazy and badly designed WAY you made it difficult. no. your design decisions were not justified at all and i suspect you will reread my review and take the criticism better this time. learn from a superior mind teaching you something, kiddo.
