I agree with the others, speed, variety, health, etc. But I would also add, that the combat system is a bit off. The attack animation is slow and hard to aim. I was running in circles for awhile to end up in a good angle just to get hit and pushed way too far back by a projectile. It's funny how the knockback is the fastest way to traverse the map. I liked that the enemies could also hit each other, but initially I expected a free for all arena battle. Good music, cute graphics, and clever story. Afterall, I had fun in the beginning, but didn't want to start over the whole thing just because of a bug.

At least I'm invincible now.

FUN! ... I vote for faster speed and a dash as well! solid work.

I really like music and sounds. Characters looks charming and have nice animations. I missed some variety of level designs and it felt like I would have liked to move a little faster. It was fun to play, great game :)

Fun game, kept me entertained for a few levels. Maybe if the character had a dash ability it would help with the weakest part of player engagement, having to run around and collect energy.

I liked  the main music and all the sounds  and it was fun to play :)

It'd be cool if I can see enemies healthbars . Also it'd be more interesting if the layout of the arena changes  from level to level and some power-up collectables arise now and then. 

Great graphics and sound, it really fits the theme. I like the crt look and the way the guy's eyes glow before he attacks. The only thing I would change would be lower everyone's health so it has a quicker turn around time but I did find that I could do more damage as I got better so maybe having a low health first guy would help people learn.

Very nice!
