I'm not the best at picking or playing platformers, but I tried a few and gave them my best shot (and failed miserably haha). All three of these are on the Super Famicom.
The first game I tried out was
Shounen Ashibe: Goma-chan no Yuuenchi Daibouken, which is based off a Japan exclusive manga about a cute seal. I have no idea what the plot of the manga or game is, but the game is a bunch of levels where you try to collect 8 things in a level as the seal. Depending on the level, it can be apples, chicks, bunnies, or something else that's cute. The collectables are either just placed somewhere within the level, or they are hidden somewhere and can be found by using the seal's head bonk ability. However, there is a time limit and if the seal touches an enemy, he loses one of the things he needs to collect. You can pick it back up again, but if it goes too far off screen it will go back to it's hiding place. This is what eventually made me quit, since in the later levels (which get more confusing and large), it was super easy to lose the collectables. Then I would have to try ALL of the places where they could be hiding again, since I have no clue where they went back into hiding. Also the seal is just annoying to control (probably doesn't help that he's so darn huge!). I still managed to beat a good number of levels though. Not sure how far I got into the game, but I beat more levels in this one compared to the other two.
The second game I tried was
Miracle Girls, which is also based off a manga, but this time with two cute girls. This one is a little more standard for a platformer, since you just need to get to the end of the level to clear it. Here you can't touch enemies, but you can throw candy at them to stun them, which also allows you to jump on them temporarily. Throwing candy is a little tricky though, since it goes in a little arc instead of just in a straight line. Something felt a little off with moving and jumping too, but I'm not really sure what. I did have to use a continue just to clear the first level though
I might have tried to clear another level or two, but right after the first level is a required mini-game that is a pain for me to play. So I just stopped there.
The last game I recently tried was
Super Back to the Future 2, which I'm sure you guys know what that's based on
This one was the most difficult for me to play since the controls are super odd to me. You play as Marty (with his hoverboard) and all you can do is speed up and jump, but the jump also acts as your attack. But the attack doesn't count if Marty isn't spinning (I think??) so if you land on top of an enemy, you get damaged instead. Except only sometimes jumping on an enemy counts?? I was really confused with this, since I couldn't figure out what counted as a hit and what didn't. Something is odd with the jumping as well, but I couldn't really figure out why. I just kept on missing a lot of jumps that should have been easy to make. I eventually stopped when I hit the first boss and couldn't beat him after using 3 or 4 continues. I sort of know what I need to do to beat him, but I just couldn't figure out how I could pull it off
So yeah, those weren't very successful choices on my part.
I might play some more later, depending on if I find any others that I might want to play, but for now I can say I tried at least
