I have a lot to say so here we go.
First the positives. The art is absolutely amazing and I love the use of particles for the thing chasing you and the hazards. the player also controls really nicely feeling super tight, snappy, and responsive. But there are some Negatives as well. Like many have already said the game is brutally difficult, it took me almost 45 minutes to complete. A lot of that is down to two parts in the game that made it kind of frustrating to play, the level design and the death.
The problem with the death is it messes with the flow of the game. The death cuts off the music and starts it back from the beginning, which is frustrating on its own if you die a lot (Like I did), it also freezes things for a second before you can jump back in again. In a game like super meat boy for example the death is fast, you hit an obstacle and you respawn at the start, no pauses, no music cuts. and this helps the game feel better as there's no pauses in between your runs and you can achieve a better sense of flow.
The other big is the level design. For the most part the level was great, It was fun to maneuver around. except for 3 big sections which are all drops. all of those parts have hazards at the bottom and its super frustrating to die to them because you couldnt see them coming, and by the time you did you didn't have enough time to react. especially with the last zigzag section maybe an indicator or a way to see the whole map before you start like Skull Binoculars from celeste would help the player feel less frustrated.
Please don't take this criticism the wrong way though. this game is still absolutely incredible and I hope it gets to the next round.
