hello. it is I. the troll. here to give a review.
difficulty-relatively easy as long as you did not turn speed to high [note-I've seen people saying 3 speed is too fast for AI level 1. I have managed to get level 4 for the ai. level 5 is definitely too fast though.]
enjoyability-high if either you play Tetris a lot or enjoy idle games.
playability-high. I have not encountered a single bug the whole time I have played up to writing this review.
advice-if you decide to upgrade speed. make sure you have a backup Ai board that does not get upgraded in case it overspeed's it. if you do overspeed. you will have to wait until enough lines are cleared to prestige or you have enough minos to upgrade the Ai. if you overspeed every board. you have to prestige.
8.7/10
edit-after writing this I realized this has not been commented on in a few months. Sad to see the game activity on a game with high potential dying.
As an idea to help on this. if you are still working on this game. I would try to add an oflline progress system. if it alrady exists and i just don't have the settings on to make it work. Then alright.
