Thank you so much for the kind words!
I'm glad the mechanic was easy to understand, I still have a lot of ideas to make it more interesting.
Great suggestions too!
1. I'll be looking into a save system for progress very soon!
2. Right now the levels are not ordered after anything but the order I made them in, so I'll definitely order them in a more natural way :-D
3. And seems like a good idea to make the game more accessible with more than just color-coded blocks.
Thank you again for the suggestions!
