Mastery #23: Uhhh, a mastery for the memes, I guess?
TrashCity 24 Sep 2024 22:12
#M212 Game #16 made it all worth it, but most of it was just reskins of the other games. It was pretty bad, I can't imagine someone paying money for this.

Mastered #1 Meu primeiro jogo de master system esse jogo e uma droga
ElMullet 1 Nov 2024 18:13
Mastery #12! Purely attempted because it was the first game on the "easy mastery" list, and I can see why. It's Action 52 levels of bad. But it has way more character than Action 52, and therefore 20 em 1 is superior. Yes, you heard me.

Platinado! Tmj

Mastery #3! I...have no idea what to say. I completed everything and I barely remembered what I did. Nothing difficult. Took about an hour. It's...the game I played in my life.

Jaysus some of the achievements are a bit pissy.

Games 13, 14 and 16 wanted me to break my controller
Reldio 22 Dec 2024 14:29
I recommend liberal use of the fast-forward function on some of these games as they are sloooow.

Mano esse joguinho é mto ruim kkkkkkkkkkkkk

You can beat about half of these games by pressing random buttons while using emulator speedup. It's certainly much more enjoyable than playing them in the intended way.

Mastery #5. What an awful, miserable game. The speed-up was a sanity saver.
tobesplays 3 Feb 2025 15:43
The best part of this garbage ass game is not knowing what number is the "win state" for a lot of these levels. Some just finish and end, some I get to 200-300 pts and nothing happens, etc.

Great trashware :D
tHcNinja 5 Feb 2025 16:51
only one that gave me a hard time was #19 . put your car in the top right corner and go.
Dankooo 6 Feb 2025 13:19
Mastered #2 - The game is filled with 20 terrible minigames, some require you to use creatives strategies to win the level. For what it's worth it gives a little bit of a challenge but overall is very easy and doable

Mastery #121~

Actual shit, game 13 in particular made me want to immediately lie down on the floor and take a nap to recover from the stress.
