Quite enjoyed this one.
I think this is a game that might benefit from metaprogression? I wish I could use the flamethrower I saw in a video of yours I think.
The dynamic gravity stuff is a very clever mechanic that makes me feel like I'm Neo from The Matrix when I run off a cliff! (Instead of just dying, like other games would have it)
I think you're on the right track.
Game runs very well on my low end machine.
