I think the graphics of this game are shit, but I also really like that it's shit. I can see you're going for the deliberately jank kinda game akin to My Summer Car. That said, the walking is very slow, the truck doesn't control well at all. It either doesn't turn at all or goes full fucking tilt. And colliding with things I'm carrying is annoying. I also noticed that things floated towards a point where you were holding them instead of just holding them, I had a similar issue with a game jam game I made a while back, I suggest just making a point attached to the player and making the object you're picking up a child of that point.
Keep at it, games like this definitely have their charm.
