This game has the potential to be good but the insane amount of the bugs coupled with poor design choices made this game so aggravating.
Lets start off with story mode. The first four times my character was not able to move. When it finally managed to work after the fifth restart the game, I wasn't able to get to the second zone because it would not load. That sums up my experience with story mode.
As for puzzle mode it was not as bad as story mode but it did take me two refreshes to actually play the mode. The puzzles seemed very easy and quite boring until you get to the boss. The boss would have been more enjoyable if your character did not stutter when she attacked. Furthermore, the fact that you have to charge up your weapon in order for you shots to be accurate seems like a dumb design choice. Not to mention, if you're charging up your attack and get hit you have to recharge it again.
The insane amount of bugs made this game so fucking annoying that I never want to play it again. For some reason if you tab the game the controls stop working. That's not including when the controls don't work at the start of the game for no reason. This bug also affected all the commands and options, for example, the command to leave the game or to bind any key in the options menu stopped working. On a final note the fact that there's little to no sounds nor voice acting made this game even less enjoyable. I'm aware that the main protagonist is mute but that doesn't mean all the other characters cannot speak. I think it took me a total of 15 refreshes in order to 'play' the game.
Overall, it seems you guys are trying to bank on the fact that it's a retro anime 2D Action RPG to justify the insane amount of bugs.
