Loving the demo, though I have some comments:
Suggestions/Feedback:
1. I'm noticing glitches with collision detection for the VSes with the terrain, as well as the salamander itself. Sometimes a VS will twitch occassionally while standing still.
2. Sometimes I can't shoot my shotgun at the internal core inside the salamander, even if I'm pressing the right trigger. Other times I can fire, and then eventually the gun locks up on me.
3. I do hope that the Salamander doesn't spew out those boxes like a fountain in the final version, because if they do, someone could hover their VS above it and just take it all for himself. Unless, of course, each player had their own boxes spawned and they could only get their own, if you know what I mean.
4. When players fall into the water, they should slowly sink down, and not fall down too quickly. You should also add a rapid-press A button icon so that players know how to swim, otherwise they'll just sink down to their death without knowing that they could swim.
5. The multi-seat VS is nice, however the main pilot should have control over main guns if they are not fully seated, otherwise it's a waste of space for the most part.
6. Would like the melee VS (shield and gun) to be able to move more freely while in the air; it has great dash, but lack of air hovering makes me wonder.
7. Flames coming from Incineration Grenades or the Flamethrower should not harm friendlies when Friendly Fire is off.
8. If all the players do well and don't die, then there should a bonus that allows them all to get S rank. Less competition and more support so that everyone works well together should be contributing to an S rank.
9. Though probably not part of the mechanics, I wonder if it's possible for a VS to have an emergency lifeboat system in the event it falls into the water?
10. I'd like to be able to grapple while in the air!
11. In the final version of the game, try to add a variety of unusual clothing/accessories, like afros, miniskirts, long leather trenchcoats, etc. Also allow for customization of the face, if possible, as some parts of the face are visible in the game, and I'd like to pimp my look if possible.
12. Special co-op missions allowing up to 16 players would be highly recommended, though a lot of akrid should be appearing in those missions.
Considering that all players have a harmonizer, will this affect how the PTX series of VS will perform? If it's a spoiler, then no need to answer. :)
Finally, splitscreen please! At least for two players! :)
If anything else comes to mind, I'll post again. Thanks for taking our feedback!
