Game freezes repeatedly(I restarted to make sure) during intro fight if you sink the center enemy ship by concentrating fire on it. This "freeze" involves a repetition of a peice of the death animation of the ship making an annoying noise. Since there is no method to contact the creator to submit bugs I am flagging this unplayable game and posting here. Needless to say I am giving it a 1 star rating.
Part of the reason why it gets so many "plays" is that they get another game's badge reward linked to it. Defeat the forest temple boss in another game Saria's song and get a pair of blue quality boots for this one. All in all I hate games like this one where there is a time gate. play less than five minutes wait 3 hours for the energy meter to recharge. The only reason why I came back here was because of the boots reward. I had forgotten the title of this game. Had I remembered I would not have bothered.
There is not enough time to drop your blocks. enemies attack before a working defense can be built up with the random block drops. This kills any fun this game had.
