I dig the concept, really cool, you have some potential there. Few things aren't clear: how do you score points - maybe have an indicator during game that shows what is your score and how do you die - the conditions aren't entirely clear for when you lose - you can have some particles that need to be dodged or something like that.
I really love the concept of consuming as much stuff as you can, that should be the main focus of the game, because its fun. Kind of like hole.io. You can be dodging particles that are bigger than you while trying to catch those that are smaller than you.
Though still, good job.
