Queen Jellyfish. 'cuz why not?
I want to play Terraria natively on Linux. Also: more musical instruments (like trumpet), more spears, Seasons, desert remake, more varied edges of the world (like Mountains on the one side, bigger Ocean on another side), upgrade for my favourite Water Bolt, ability to sit (and maybe crouching/sneaking), ability to throw NPCs (suplex rampage ). That's all for now.
Oh, one more thing: I want "Huge / Very Large" map size so bad. Comparison:
Large Map (8400 x 2400 blocks), around 5 Floating Islands;
Huge Map (16800 x 4800 blocks), around 10 Floating Islands.
Could require a special drop from Spazmatizm.
