Hey! I really enjoyed the game, it was incredibly enjoyable and overall fun to play as well as well as fairly challenging! Good luck with further developements!
Glad that you enjoyed my game, I enjoyed your video too. Don't be very harsh on Jeff, he seems to be a nice guy :)
I want to clarify some points.
Both of us (me and McMillen the developer of Binding of Isaac) used old Legend of Zelda games as inspiration for our creations. In fact Knightin' is more similar to Legend of Zelda: Link to the Past than Binding of Isaac. It was an amazing game by the way. A real masterpiece. You should really check it out. I bet that you'll really enjoy it. Just use any free emulator if you don't have any old Nintendo console.
Also I made this game all by myself. But it took me 16 days actually. Pixel Day didn't have very strict deadline ¯\_(ツ)_/¯
