Ouch my ears :( The sound effects are so much louder than the background, I had my volume turned way up with headphone to listen to the background track, would be nice if you balanced it a little better.
The visuals are fantastic! I loved the 1 bit art and the character seemed to have personality just by the way they looked. That's a sign of really good character design in my opinion, great work!
The shoot and teleport mechanic was fun as well. Would love to see more levels and challenges with this mechanic. And maybe a story for our main character too! Hope you keep working on this, there's a lot of potential here for a really good and popular game.
