This has a awesome classic feel. My mech is Heavy, Strong, and Powerful. Already there is a good skill curve where skilled pilot is much more effective than a noob.
The UI was clean, intuitive, and easily discernable.
It is incredible to see what you put together in just a short game jam, and I would absolutely pre-order the finished game now, based on the visuals and quality so far.
Particular details that I like:
•The sound design, especially when opening and closing the cockpit
•The HUD is projected onto the cockpit window, and cuts perfectly with it
•The tradeoffs between heat, mobility, and firepower
•The different subtle uses for the different weapons.
You probably have a bunch of things to add to your game, but if you continue it, here are some things I'd like to suggest:
•Controller re-configuration axis by axis (I want to use my old joystick and such)
•Missiles locking on if you look at the target long enough
•A shield to equip which would prevent all damage, but use up heat instead
•the ability to harvest cool-down charges from your fallen foes.
•moving faster but taking more damage if the cockpit is open
•Quietness as a game mechanic, where if you move slowly you are less detectable on the radar and such. (more reason to open the cockpit)
•I SO want the ability to destroy the trees with my missiles.
•A button (middle mouse?) to align the legs to the cockpit automatically
•of course even more weapon options, and a load-out so I can pick between what is equipped. (some of which wouldn't be weapons, but instead extra coolant, speed boosts, or armor)
•a radio in the cockpit to switch on to play one of 3 types of music or not. (Cause why not?) or for a voice chat. Of course making more noise makes you more detectable
•and a super simple thing called multiplayer. I'm sure you could just toss that in easy (sarcasm)
• and along with multiplayer, some mission modes such as capture the flag, and king of the hill
