Thank you so much for the feedback!
The touch screen idea is really sweet, worth exploring.
I totally agree with your take on the difficulty curve for that satisfying puzzle feel - it is definitely a miss on our part and a learning experience as I messed up on the scope of the game, so even though the difficulty scaling factor was there in design, we had to choose between new implementation or bug fixing. XD
Thank you so much for playing and definitely glad you enjoyed the art and the win sequence!
