;----------- TO-DO -----------
;-----------------------------
-; Shiar 3.III.00
+; 92% = DONE
-;Feel like doing something? (name indicates who's working on it)
-; * linkplay
-; * singleplay ending
-; * titlescreen
-; * make linkplay available for all gametypes (not just deathmatch)
-; * two worms collide with heads -> both should die
-; * game types:
-;1) * ctf: take enemy flag (right-bottom) and return to your flag (left-top)
-;1) * domination?: take control points by running over them and hold them
-;1)* sprites for picks instead of blocks
+; * customizable keys
+; * internal levels
+; * check levels/gametype
+; * enough hiscore saves!
+; * complete readme
+; 2% * misc (pollish, bugs, &&&)
+; * LINK
+; 2% * fix deaths linkplay and transmit game/level data
+; 2% * make linkplay available for all gametypes (not just deathmatch)
+; * CTF
+; 1% * fix pea XOR problem in ctf (+dom?)
+; * fix wormstop
+; 1% * domination?: take control points by running over them and hold them
-;1) Working on a new pickup-system allowing more than one "food" and different pickup-handling
+;100% = bugs fixed + levels done
