Hi, thank you for your feedback! It is very much appreciated and is something that we have thought about as well. We made the levels intentionally easier because you will find that most people skip the game if it's too hard. For example, I played your game earlier yesterday and I couldn't get past the place where the skin comes, the game mechanic was a bit hard to understand as well. I think for a game jam we should be aiming at an easy skill level (that gives me an idea to include maybe three modes in our game - easy, medium and hard) We also wanted to create a reward system for using less tiles - but only so much you can do in 7 days. I agree about the use of platforms being redundant in certain levels - it certainly needs a bit of polish there.
I'm glad you enjoyed the game and your feedback was amazing! Thank you for taking the time :)
