good game :)

Cool design and smooth gameplay. The bullet guys are so hard to get around. A little variation in their attack could go a long way I think.

This game idea is incredible and was executed really well

this was fun to play through. my best score is 72, that's when I get overrun with bullets. I wish I had more space to move about, but that restriction makes this game even more challenging and drives me to get better and better at maneuvering, although I rarely used the heating up mechanic, which is probably one of the reasons im not doing well.  Having the tutorial be the first thing you see, allowing the player to try out their move set is really nice, usually im given a block of text and am immediately pushed into action, so this was a breath of fresh air

I think the game has potential as it's pretty fun to play but it needs a better and consistent art style.

It's the start of a potentially good game with a nice balancing mechanic, I think you can improve on it a lot in every aspect.

Really Cool Game, I Didn't Really Know How To Play At First But Later The Game Felt Really Good After, I Like The Art. That All, Good Game ;P

Fun

Quite fun, I loved the random hard mode. Had me on the edge of my seat trying to survive.

Nice idea having to balance the heat bar while fighting, made it quite fast paced.

The idea is awesome and I can see it being expanded into a full game.  The current version needs a little bit of polish, but overall great entry!  

Really good game, had a lot of fun playing it! I just wish it had more weapons and enemies but other than that this is a solid game.

Nice game with a cool concept. The Heat Bar is really interesting with the heating and cooling although I mostly only cooled the robot. The Controls feel good. Some enemies are a bit hidden behind the hearts at the top. All in all, well done.

Nice use of the theme. The dual heating/cooling system is an interesting idea that deserves more exploration. Controls are fairly smooth. The layouts of the enemy waves were clever, and surprised me more than once. I grinned to myself when I got to HARD MODE. :)

A few suggestions:

I would make the heating/cooling setting (hot vs cold) visible even when the bar is at zero. I expect that the current setup is intentional, but I still found it a bit confusing.

The flamethrower should display a stream of fire originating from the player. It took me a couple of plays to realize that it was me damaging the opponents. :) 

The music gets grating after the first few seconds.
