well I jsut replayed the thing and managed to get stuck in the most likely final area of the game.
well, just the thing is I kind of missed the attack upgrade this time (cant remember where the dang thing was again)
so I cant attack the final boss. and getting back up is impossible due to red snake like pattern on the left wall which I would have to climb.
softlocked is probably the right name for that.
even though i doubt anyone except me would try to get past all the big red dashing and jumping squares without any attack abilities :-D
