You really have got something special in the making here. Your pixel art I really like so give yourself some credit. It's clear you have spent much time on building a really good look for the game.
The music and sound effects are also coming along nicely. I like the chilled out tune! One little suggestion if you don't mind.... For me the sound of Kal running up/down the stairs could do with being a little deeper, more of a thud than a click. Only my personal preference!
Keep up the great work and I look forward to seeing further updates.
