I am in the design stage of my own YN fangame, and just want to share my random thoughts (btw, I'm the lolwut guy)...

• A big problem with YN-type games is that it can take forever to get to some places. How do you guys feel about some kind of 'warp' effect that can take you to the more out-of-rech place?

This would work by:
1) Obtaining the actual 'warp' effect.
2) Activating an obscure area's 'warp point', if it has one.
Really, I guess this is a souped-up Medamaude.

*Money. Now, it doesn't seem that there's much to do with money if you go to the trouble of obtaining it. Some thoughts:
1) Sodas should have short-term effects. Right now I'm thinking speed boost, like you're character's on a sugar rush.
2) Gachapons! Scattered around the dream worlds will be gachapon machines that will give you a random figurine. There will be different sets to collect: mecha, showgirl, etc. They will be displayed on a shelf in your dream bedroom.

EFFECTS

• Headless. When equipped, all sound is muted. This may or may not play into a gameplay puzzle later on.

*Spider. The player can walk over wall tiles, to climb hills etc.

*Camera. You carry a camera and can essentially take screenshots. These can be kept in a photo album to look at. I'm also thinking that you could be required to go 'event-hunting', where you need to photo unique creatures/areas.

*Slime. You can step on liquid tiles and absorb them. Once you have a liquid inside you, you can use it on creatures/objects/etc. For example, absorb water and use it on a fire to put it out.
