Everything works perfectly, keysettings you can choose make it look pretty legit.
Some kind of anti HD and FL hack, you can set AR, slider width and the colors. Didn't really used it since I think playing with that feature is confusing a lot. But everybody up to him. The feature itself works well.
Quite a few ones you can choose from. Obviously if you don't want to get banned, you won't use them online. Also quite a few creative ones like Middle and Random, tho, I miss the circle one a little bit, if you know what I mean (where the cursor moves in circles to the next hitcircle.
Not much to say, it is a relax mode for the Taiko mode. Same as for the Relax hack in Standard mode, you have lots of randomizers and settings and with the LCTRL and LALT keys you can also vary the hitwindow in game.
The only thing that I would still add is to apply the hack on drumrolls and spinners.
Same like in Taiko it is a relax mode for Mania with Hitwondow randomizers, adjustable key hold duration and with the LCTRL and LALT keys you can also vary the hitwindow in game - like in Taiko mode. There is one just thing I would like to be added: A hotkey like LCTRL and LALT but when you press it the hack stops working for the duration you are pressing the key.
For Standard it worked perfectly. There are just two points I want to mention, playing with it in OSU!CTB it won't slow down your fruitcatcher, which means if you play with a speed of 20 % you still move with 100 % of speed. Which is obvious. Also in OSU!Mania it won't slow down your scroll speed. And if you play a 11* 7k map with a scrollspeed of 40 it is pretty obvious as well.
Also I understand that the Standard mode has a higher priority than Mania and especially CTB.
I experienced quite a few bugs but Helmerz was absolutely awesome and helped/fixed them as soon as possible.
Had a great time using it, there are so many settings you can configure. Also the Help from the creator was awesome. Can just recommend to buy it so Helmesda can waste it.
