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.

Not sure why this doesn't have more ratings - it was quite well done!

I really enjoyed the art style and the cheeky "only three colors on-screen at once" use of the restriction. It wasn't super clear what the different emotions did in terms of impact, which I feel was a bit of a missed opportunity if there was supposed to be a difference there (it seemed like there was, based on your description?). The SFX were a bit "blinky" I guess I'd call them - sort of noisy in an arcade-y kind of way, but that stuff is hard to balance, so I get it.

I must say that the dash was a weird inclusion to me. Like, I get it - you want to give the player the option to move more quickly, especially in a world of avoiding many projectiles and traversing a space that's larger than a single camera's view surface. However, when adding something, consider why; if the player has no reason not to press dash, then don't make it a button to press at all and simply make their movement speed higher (here, they don't have a reason not to dash, as the enemies only have collision-boxes, not damaging flags, as far as I've seen). 

Still, the polish here is really nice, and it complimented your emotions mechanic well (could have been even better in terms of mechanical clarity, but you brought something unique already, so..).  

Very cool art, looks like handrawned giving it a Unique Style. Controls and mechanics were simple and understandable. I really like small details like the "Emotions" moving inside the bottle, and also cool game cover. I wish there would be multiple smaller levels before the boss battle, that would help the player to focus on moving forward rather than wandering around in a larger area.

Pretty cool, keep going! Thanks

Really nice idea for a game! Good flow to the game, but I wish there were more levels and mechanics. Nevertheless, I had fun playing the game!
