I just replayed the game and tried to reflect a bit on why I felt the way i felt so you could get some reasoning around what i said.
I figured the laser would need some better telegraphing(idk how to properly spell telegraphing) because i could not see the connection with the explosions at first. Thats why the timing was so damn hard to get when trying to deflect the lasers. But when i read about the double cue and looked for it in the laser i could see it. But because the laser were so busy with other effects i couldnt see the cue. So either you could lower the amount of the other effects around it or increase the opacity of the "pulse" effect.
Also when i hear a double pulse, i immideatly figure to press when the next puls would come and i think a lot of others do as well. The problem is that you have to tap BEFORE the pulse actually comes. Even though the brain wants you to tap on the beat you have to tap before the beat, it goes against instinct. So maybe you could make the pulse attacks (laser and explosion) actually do damage a few frames after the "imaginary beat". A terrible explanation, but imma roll with it.
The hitboxes of a lot of the bullets is bigger than the actual object, at least it feels so when you play. You can generally make the hitboxes of bullets in "bullet hell style games" smaller than the actual object. Just a tip, but i recomend to try it out and playtest it. It will feel easier and a bit less punishing.
I think the reason why I disliked the new music is because it is so sudden. The hihat just comes outof nowhere straigt into your face and its pretty loud, wich is not helping, generally the new song is so much more intense. So it would be nice with a transition song between dream 2 and 3.
On the assistmodes it sounds good.
A debug mode would be really nice to have where you can see the dream your at, the level of the dream and go back and fourth between levels with a buttonpress. (bonuspoints if it is activated by simply writing "debug" on the keyboard ; ) ) that would make
the hitbox is off so all the characters is floating.
To get to the secret you have to move the ball thing trough the floor and it just looks like a bug.
Thats all i had time to write because the gmtk game jam is starting soon, ill write more when its done : )
