Awesome little platformer! The artstyle is definitely a 5/5 for me - simple, aesthetically appealing with lots of character. At first I worried the gameplay might be a little bit too simplistic, but a soon as I reached the first upgrade things definitely got a lot more interesting for me! I really like the metroidvania aspects of this game. Being able to dash through a wall that was previously inaccessible was satisfying progression.
My only complaint is the combat not being as punchy as I would've hoped, and the lacking audio.
Regardless this is a really good entry! I enjoyed it.
