This was a cool game that I was engaged with right away. It has a lot of potential but at the same time a lot that could be expanded upon/improved to really hit a high.
First the basics:
The controls were very weird to me, while they were basic enough to not be an issue arrow keys + z x c feel like a much more natural fit for the type of game this is. Of course any control scheme will have someone complaining until you make them fully customizable and this wasn't a huge deal.
The art was great, it pops out and is easy to understand but still exciting in a lot of ways.
The one oddity was the boss, who looked like they were from a different game due to not having a dark outline, using dithering for shading, and using a generally less saturated palette than the other characters.
For the player feel: overall good, albeit slow. The dashing was very satisfying although it didn't really seem useful in the level outside of getting a head start against the boss to fit in more punches before needing to move again.
The enemies were cool but didn't feel threatening given as long as you were punching you were basically untouchable since there range was shorter than yours and punches stunned them.
If the player had faster movement leaning in on enemies that shoot at you while you generally need to get in close to punch could be a really cool dynamic.
Speaking of faster movement I feel like the entire game could be speed up 1.5x and feel a lot smoother.
Being said the core mechanics felt good, and it felt good having this character beating up bugs, with the character design being a big plus in it being engaging.
