Sqdef is a tower defense game for the GP2x.

Changes:

-> A new tower, the Scythe – so powerful you can only build one
-> A new factory, the Trapper – slows targeted enemy by 25%, has no effect on bosses
-> No more Dual Armory: now you upgrade the regular Armory in order to double its range
-> An icon that shows whether fast-forward is on
-> Cosmetic improvements all-around
-> A badge replaces medals on maps where you beat 60 waves
-> Some new coloured creatures, more wave variety
-> Editor does not allow maps with more than 20 possible paths
-> Compatible with 1.2(A) hiscores and maps; old saved games will be automatically cleared
