Really fun controls! Could definitely be expanded into something bigger :)
I got up to the start of 1-3 but then my browser reloaded accidentally (using the right click for controls sometimes opens up a menu in some browsers, although I think it was definitely the correct choice for your game) and I kind of stopped playing then. Really unfortunate because I was really excited to see the boss being upset at me, from the NPC in 1-1.
Only a small piece of feedback, I feel like you should stop the player from moving while the level card shows up. It's weird to sometimes start the level and be in a weird spot
