A good, creative and innovative rhythm game that solely focus on rhythm. Hard and challenging but addictive to proceed to the game. Now  purchased the paid version and finish beating all the levels from the base game except XO-X and XT-X. Except some text errors shown in speed trial mode, not much problem encounter during the game play. Generally a fun rhythm game to enjoy, hope to see better content of this game in the future. Glad to discover such gem in rhythm games. Thanks for making such a good game to enjoy and challenge.

Edit 1: Finally, after 235 attempts, I beat B-X in original speed. Up to now, I beat all the 12 main worlds with their minimum speed trial target, completing all Neo Cosmos level (with checkpoints, and including all the EX worlds), bonus world, extra 6 worlds and the first two muse dash collaboration levels. So that should bring all the 44 achievements if this is the Steam version. (36 main world achievements [12 blue lantern for pass, 12 yellow lantern for accuracy exceed 100%, and 12 red lantern for completing at least minimum speed trials target stated for every main world], 2 bonus achievement {complete B-X and game 100% complete} and 6 Neo Cosmos achievements (5 for complete 5 main worlds (1 achievement for each world) and the last one for completing the 4 EX worlds); so total= 36+2+5+1=44). After playing the game, yes, I noticed using a desktop keyboard usually gives you the best gaming experience and make the game "easier" to be played compared to other inputs. So, what I am going to do now is to buy a desktop keyboard, connect it to my laptop, and use it to do the same thing that I have done in itch version to the steam version in my laptop in the same timing window. Hope that this time I am able to do it again. Good luck for me!

Edit 2: Finally again, after 80 attempts, I beat ML-X in speed trial 1.1x, and eventually accessible to MO-X. This level is hard because of it's fast tempo and complex rhythm concepts. Through this achievements, I also discovered that using space bar as one of the main input buttons on keyboard may help to beat difficult levels as it produce greater clacking sound and able to press faster compared to other key. Recently only left with the world XO to beat through. 

Edit 3:  Finally again, after 470 attempts, I beat MO-X. Now left the two levels on crown island. I will find time to beat them later. 

Edit 4: The game updated to a newer version (V2.0.6) but it's only for Windows 64-bit. That's become the reason why I can't access this newer version of ADOFAI. (Including the neo cosmos dlc too). Unless the developers made a 32-bit version for the game, otherwise I can only access it when I changed to 64-bit operating system.

Edit 5: Thanks for uploading 32-bit version. However, please note that there is no music for T2-EX to be played throughout the levels. If this shouldn't happen, please do fix the bugs. However, what excited about is, I finally pass XT-X Options on normal timing window. For sure will find free time to beat this one last level. (The music bug of T2-EX has been fixed right now)

Edit 6: The steam version of this game had added 3 new achievements. First one requires to beat MN-X and ML-X in normal mode with checkpoints. Second one requires beating all the 6 worlds on Xtra Island. And the last one requires to beat 6 Extra world's speed trial challenge. The first two doesn't caused much problem as I had already achieved them before. The last one was really not easy to tackle with. Took me 2 days to beat through the itch version. So now, I should get all 47 achievements now (previous 44 in Edit 1 plus 3 achievements stated above.) 

Edit 7: FINALLY! After 2 to 3 months of hard work, I have beaten World XO: One Forgotten Night in my itch version. So, for itch version, I had completed every single level in ADOFAI. NOW just need to redo everything in the Steam version. Hard works of 2 to 3 months had not been wasted. (Also, there is an major update to v2.1.1(r98) during these times)

Edit 8; After a few months, Completed every speed trial for main game and DLC (Except for XO-X speed trial, it's just too hard for me).  Probably great achievement in my life. 

Edit 9: After a fee couple months later, I have beaten the last seed trial for World XO in minimum speed trial target 1.0x. So, for win11, all lanterns are retrieved. Just have to do this on Win 10 steam version and Win7 itch version. Then, I will finally done eveything about adofai right now. 

Edit 10: Yes, completed Win 7 ones. This time took me longer than expected. Nownjust left with the Steam version. 

Edit 11: All lanterns achieved. Task done. 

P. S. I swear I won't try speed trial levels anymore. 

Suggestion: It's better to purchase the mobile version first if you are not great as mobile version are usually having a more lenient timing window, which can gain you  confidence to beat through PC version.
