Maybe I'm reading the handcannon sprite wrong
No problem, in any case.
The frag grenade is basically unchanged, literally removed 4 pixels to make it a little less square.
I might try redoing it for more of a slim MK. 2 look. Slimming it down a little and muddying the bright green should make it feel a bit less Worms.
Dioxine, do you have a preference for things looking like strict pixel art, or more rendered and then palletized, like the javelins or soy sprites?
