Thank you so much! :)
I usually try to omit an explicit tutorial, but try to "teach" the concepts through basic levels first. Did you notice the "How To" Button on the bottom right, and if so, did it help at all? I'm experimenting a bit with the way i can give more explicit help ingame, without frontloading it.
Was the tile flipping the confusing part, or anything else? Can you tell what made it confusing? Sorry for the many questions, but it would help me out a ton :)
update: tried the how-to button and yep, would've set me up well to understand the base mechanic of the game. my recommendation would be to have that screen that pops up be an overlay the player sees the first time they attempt the first level (and still have it accessible from that button), OR make the button a lot more obvious (you could even have it flash if the player fails the first level many times in a row). because if i had known it was there i would have absolutely used it. from my perspective, i think based on the size of the agar grids for most of the levels you definitely have room to at the least make the UI buttons larger.
