First off: the art design it absolutely wonderful! Definitely one of my (two) favourites this jam. I also like the idea of “bottling up your feelings” and its quite literal interpretation. This also fits quite nice with the expression mechanic. (I’d almost expect the blue bullets to be tear-shaped.)
As already mentioned by others, the actual implementation of the feelings/colour is somewhat clunky:
- The difference between the colors doesn’t become quite clear during the game.
- The current colour is somewhat random, as it’t just whatever you picked up last.
- You basically never run out of feelings, i.e. reach 0%. Instead, you have to be careful to not accidently reach 100%. (You collect lots of feelings, and the enemies don’t require much to kill.)
These points make the colour/feeling mechanic in its current form hard to notice. I think this is somewhat sad, as it seems to be a fine idea that fits together nicely with the art style.
