This is a really good concept for a game that you collect DNA to grow and powerup. The artstyle is amazing - the main player character and its animations of boxing were superb. The map and enemy design was also really cool, fit the vibe of the game! There are a few suggestions i have to improve upon the gameplay - The boxing currently happens in 2D, so if the enemy is 'in front of' or 'behind' me, there is nothing I could do to hit it, so i had to align myself along the z axis to hit. I think if you can do something where you maintain the '2.5D' kind of feel (which i really like btw) but also address this issue, it will really help to make the combat a lot more fun! A little bit of variety in the enemies will also be interesting so that the player can really think about which upgrade to take when. Good job overall and hope you turn this into a full fledged game some day!
