Thanks for the feedback!
I'm still tweaking the throw mechanics. GB Studio locks movement of non-player sprites to a grid, but player walking is flexible, so it can be a bit disjointed and that throw spacing is a byproduct. Hopefully I'll figure something out.
As for the push block issue, I can't figure out a clean way, aside from lots of bruteforce coding, to get collisions on a block in GB studio. If anyone has used GB studio and has a work around, I am all ears.
The clipping issue is completely news to me! I'll try to fix that (but it's also kinda cool).
