Firstly I had it not visible at all. I implemented the barely visible "circle" one day before release because I thought that people never would think about clicking on things because no other novel (at least none I played that is comparable) has such a feature. I'm open for suggestions for the coloring and overall shape.
Well I guess simplest way would be like a lit up colored outline around the object. Like if this was objects in a sandbox free roaming point and click I'd be down for finding these things in the environment organically, but because it's during dialogue and clicking anywhere on the screen advances the text so you keep having to hit back or rollover back to keep trying things, it's more irritating than fun. Some people might not mind that but for me if that's how it has to be done, just constantly trying and hitting back to try another thing before I actually let the text advance it's motivation for me to not look for them at all.
I guess aside from that as far as any criticisms go, the only other possible minus would be that things are often not animated just still frames advancing one at a time, but I know that's common in the genre, I'm not sure if you're gonna go for more fluid animations or not. I'd say I have a preference for smoother animated scenes but if your focus is more on the story and writing rather than on animated scenes that's fine.
The story and characters so far are good, I like the character models a lot, freckles are definitely hot so I'm glad to see LI's with them.
