Very interesting little rpg game you got here with a very fun and clever concept and mechanic. I'll admit I was pretty confused at first as how I was ever supposed to get further than 4 jumps, but understanding I could unlock shortcuts made everything click into place. I managed to beat the sandman without even using what I assume is the final shortcut.
I felt like the theme was well incorporated here as traversal, healing, and damage boosting mechanic. I am always a fan of when a developer managed to bake the theme into the gameplay itself. I think the gameplay, particularly the combat, could have had some better balancing. For the most part I just spammed attack and it worked. I focused when fighting the pillow and guarded with fighting the guy that was winding up, but other than that I just attacked. Maybe some combo multipliers or more unique and varying attacks from the enemies. The art was cute and crunchy, reminds me of an old gameboy game and the audio fits to it, though maybe a little loud. Overall, I think this is an excellent entry and I think on of the only true rpg ones I have seen, so hats off to you for taking that on. You made a pretty fun game that fit the theme well and had an engaging challenge. Well done! You should be proud :)
