This is both a little game and an actual thread. It depends on your mood.

You could do something serious, IE: If you have trouble with mazes, don't play Monkey Island without a guide.

Or something less so. IE: If you have trouble with the Goombas in Super Mario Bros, maaaybe don't play Super Mario Bros. (They walk in a straight line and are easily evaded.)

If you have trouble with trial & error gameplay, don't play I Wanna Be The Guy or Long Live the Queen.

If you have trouble dodging thousands of projectiles all at once then don't play Touhou (or at least play on an easier difficulty)

If you have trouble with poorly designed adventure games, maybe don't play Teen Agent.

Oh, it's poorly designed?

If you have trouble pressing lots of buttons at once, don't play Guacamelee. (Colorblind players might also have issues with enemies that can only be hurt with a specific attack depending on color.)

If you would rather not spend hours doing nothing but fight enemies for XP and gold, don't play the original Dragon Warrior.

If you have trouble with Super Mario Bros., don't play Super Mario Bros.: The Lost Levels.

Well, most adventure games of this type present reasonable challenge in determining what items are useful in certain places, and are generally straight-forward (or sometimes quite clever) in giving you clues where something might be important/useful (LucasArts & Sierra being the forefront companies). The plot, script and music of these class of adventure games were also polished to a fine quality. Teen Agent failed for me in all those areas. Nothing but an irritating item search, with little logical ways of solving the puzzles beyond "try everything here", with an unlikeable protagonist and comparibly dry in the humour department. It might "look" visually ok, but that's about it for me.
I enjoyed "Ben There, Dan That" and "Time Gentlemen, Please!" far more for the time spent.

Have you ever played Igor: Objective Uikokahonia?

The name sounds like something a torture victim would scream while having their nuts fried. Gameplay have a similar effect?

For the most part it is a typical 90s adventure game. Then, in order to pass from one area to another, you have to solve a maze in the catacombs of similar looking areas.

If you are having trouble catching that goblin over the roof tops in M&M's game DM then be like me.....ahh forget it!

If you have trouble understanding this thread maybe don`t read it.

If you have trouble finding a girlfriend, maybe don't play HuniePop. It won't help.

If you have trouble finding your orientation, don't play Daggerfall.

To be honest, I've got different opinion than Braggadar.

Looking on puzzles in the game, most of them seems to be relatively fine and basing on some reasonable premises (e.g. puzzle with making from cookie suitable "gift" for girl; obtaining nut which has fallen into grass, getting out from closed room). Comparing it to completely random and irrational model from first Sam and Max (the one from Lucasarts, not series from Telltale), Teenagent is making much better, despite the fact that Teenagent was made by small team from Poland.

Humour is a bit "hit and miss", in general - I like it (aside from a couple of not especially funny jokes). However I guess that due to the fact that I've played in polish version, I could have there vastly different impression.

Only thing which I didn't like was at the beginning of the game, where I couldn't figure out how am I supposed to use equipment. Other than that - quite good, even if a bit "low-budget" game.
