This game is so much fun! It also feels really good, nice use of juice lol
I noticed you used the groverburger g3d engine. How was it working with it? I've been tempted to try some 3d projects in love!
Sorry for the late response.
G3d is really good if you don't mind missing out on animation systems and fancy shading but you could always implement those systems yourself if you really need them. It's pretty much like making anything in LÖVE where it gives you the bare essentials in a simple and approachable package and doesn't get in the way of making whatever it is you want to make. Honestly I think Lead Haul would have taken longer to make in a proper engine like unity, godot or unreal since g3d is free from a lot of the clutter and bloat that you have to put up with when an engine is built with commercial games in mind.
For what it is worth I have been using g3d for over five years and I have no regrets so I can't recommend it enough :)
