Wow! This is one the best reviews, if not the best so far! You are totally right about the last row. On phases that has enemies shooting faster bullets, the strategy is to clear the last row first and then the rest. About the slow pace, yes you are also right. I don't think another threat would be the way to go, because some phases are hard as it is. The use of time is actually interesting,I don't know why I didn't think about that. Although to implement this system, I'll have to test every phase to calculate the average time I spend to finish it. I'm not gonna be able to implement it right now, at least not these week, but in the future sure! This review is very enriching not only from this game perspective, but from all gameplay in general. Thank you very much for this, I've learned something!
