I used to play flow free so much back in secondary school and hadn't thought about it in years so you can imagine my surprise when playing such a similar game. I think it's a very polished experience that feels almost like a full game; there's so many little details you got right with how cosy it makes the game feel. The bombs exploding is not only a great connection to the theme but also a fun way to end each level. Love the music too.
I personally found levels 12, 13, 27 and especially 30 the hardest. Level 30 had me stuck for so long that I gave up lol. I agree with Donutsforlife's critique about how some mechanics weren't utilised enough and how the difficulty didn't scale well because outside of the levels i mentioned, it felt like a breeze to get through most the levels. Good game though!
