I just played your game

aaaand holly crap I loved it

it is FAR from perfect but the music and effects were glorious!

like seriously

Ok detailed feewdback

First and Foremost I loved the effects and the buildup to the music it was an experience

the crazy flashing visuals were beautiful

but...

that doesn't help in a precise platformer....

and that seems to be the biggest issue I have with the game is the level design, which seems rushed together at the last second (just like my first game jam game)

the visuals were amazing except for the second one you get the flashing blue squares

it was obvious they were tethered to the player in some way and the random white flash is neat but it really messes with the platforming

What I would do if I were you is take your current engine and items re-design the level so it is cleaner and jumps are not as percise

instead maybe make the player faster every time they get an item to really emphasize the buildup in gameplay

with their speed they can make jumps they couldn't before to unlock new paths

If you do that you have a really really solid 5 minute experience I'd love to see at the top of Itch.io

I was great. It needs polish but if you work on the game for like one more day you could make it into something truly special. I have played over 300 game jam games and without a doubt this is the second best I have ever played.
