I totally agree with you on this, and most of the instruction text weren't there originally, but ALL of my playtesters they were confused on how to progress the game, and quit because they either didn't know what to do, or thought that the game was over, and since i didn't wanted that to happen to the player, i choose to add them, even if it "muddies" the experience for some players :P
I guess adding an hint system could have been a better option, too bad i thought of this only now :/
Thanks for playing (and hopefully enjoying) my game!! (^u^)
