Cool game and concept, the movement felt clunky at the beginning but when I got used to it, I had fun with it. My only problem is that the view distance is barely enough to see incoming walls, especially when accelerating, so it's not easy to speed around without crashing into walls.
What I'd like to see is a better tutorial, as pretty much nothing is explained. Inventory system is not explained, there's no comparison between equipped and hovered items, and the UI isn't explained either, I spent an entire level without realizing there was an ammo count. It was obvious after I saw it, but a tutorial would have been much better. I didn't understand why I couldn't pick up stuff 'cause when the first level ends, items are added to a large inventory automatically, but in game, they go into the backpack. Still obvious, but not before taking the extra time to manually check those details.
Also, the game should be paused during the tutorial screens, as I had to skip them to not die to the enemy at the spawn, which then led me into wandering around thinking that I had to pick up an item for the portal, 'cause I didn't realize that I had to stand for a while before it activated and I didn't have the time to read anything.
Regardless, I had a ton of fun and I hope my feedback helps you! Best of luck, looking forward to seeing it on Steam :D
