It's a pretty good demo. Although there are some issues that I've experienced

I have used the webslingers a lot and they're definitely my favourite, although there is some jank to them. Like when you go to make a fist. You can't actually fully close your fist otherwise you just shoot another web, so I just resorted to web-slingshotting myself at enemies at Mach 3 speed to deliver the most devastating poke known to man. It would be super call to have like a different firing mode to ensnare them or make them "harpoon" onto surfaces like the real Spidey does it.

The thrusters, WAYYYY TOO FAST, and their only purpose is mobility but you can't really control it. If you feather it, then you activate some kind of ultra boost burst even tho you're already going so fast and you just end up hitting your head on a wall. You basically just end up roleplaying as a human torpedo. Also, there is no real point to this power if in the full version you can just fly like Superman, my suggestion would be to make it a more cosmetic or a alternative to flying when the full game does come out or the next patch.

The energy blasts are cool but you literally would do more damage to the enemies if you sneezed on them or gave them a lil tickle. It would be super cool to see different firing modes, similar to the webslingers, such as if you hold the triggers down and next to your waist, you'll be able to do a Goku style kamehameha or a massive laser beam like Iron man does.

The weapon summoning is cool and I do understand that it's a demo and you can't change it, and I do see that in the trailer you use a bo staff/spear, but think about not only traditional melee weapons but like Red Hoods guns or like Daredevils billy clubs.

A suggestion for another power/weapon would be magic or mystic arts, similar to Doctor Strange! Imagine doing gestures or specific hand motions to summon a floating sword or a runic sheild, or chains to trap enemies/whip them across the face!

Other than that, it's a pretty cool demo and I have put like an hour or so into it. It definitely has massive potential and I'm aware that this is in very early development. I'll be sticking around for future updates on your game. Nice work so far, keep it up!
