So glad you enjoyed it, and I appreciate the feedback. I'll definitely be refining the randomization of platforms and items as I continue development.
Yes, I would suggest doing a first level really introductory to the mechanics... you can even have 1 level without the rising water/lava so you present that danger in the second or third level and that makes it more engaging to the player... because he/she though it was all easy and cannot accept too loose his previous success feeling. :D
