I played the browser version in Firefox.
I found it was too difficult to collect the hearts, as the pink dragonfly appears to have more agility than the blue dragonfly.
I like the camera math.
Overall: did not acquire dragonfly girlfriend
Fun: I liked how I can splash the pond water
90s: it appears this is a 320x240 rendering. I don't think Sega Saturn could deal with this game, particularly due to how detailed the background/bushes/grass are. Dreamcast should have no issue rendering this though. I appreciate the lack of screen filter effects.
Visuals: The art direction on this game is absolutely fantastic. I enjoyed the style consistency between the pieces of the scenery.
Sound: I like the synth instruments. The "beep" sound effect could use some volume envelope adjustment to make it a bit more pleasant.
