Hey there!
First of all, congrats for finishing the game! I have to say right away that I love the pixel art, the game looks amazing. I like the sound effects but some music would be great. The gameplay was very smooth, however, it was really hard for me to use WASD to move, C to dash and Z to hit, I had to play with my both hands on the right side of the keyboard.
Other than that, it was a really fun game with great looking assets. Congrats, you did an amazing job!
