Well, I played some of those Humble Bundle games.
Samorost 3 was a artistic point and click. Puzzles were weren't really hard, mostly just a matter of figuring out how it works, then it's quite easy to actually solve the puzzle. Buuuuuut, hard puzzles in point and clicks are about as fun to me as a playing against a racist hacker in an online shooter, so that's not really a problem for me, quite the opposite. Plus there's even a hint book if you need an idea of what to do next. Besides that, I found the art style and graphics just marvelous. detailed, varied, and alive with everything that goes on in the levels without being overwhelming. Story's simple, young Main character goes on journey to help musical monks against one evil monk, but really, I think the main focus of the game was to be about exploration and puzzles, which I say it does excellently.
Besides some minor complaints, it's beautiful, the music is a pleasure to the ears, and the puzzles are fun.
As for another game, Caveblazers, think Binding of Issac plus Shovel knight. Pixel action platformer rogue-like that really, REALLY RNG dependent, and that's my main gripe with it. Whether you ahve the gear to fight the next level is completely dependent on whether or not RNJesus blesses you with divine digital fortune. Sometimes I can go through multiple boss fights and not get anything better than my starting melee or ranged weapon. There are also some unbalanced aspects, such as the fact that healing shrines have ridiculously high price spacing. They increase as you get more health and progress, but by the end, I can't imagine someone being able to buy them unless they either bought very little else in previous levels, or fortuned upon one of the perks/items that offer higher gold boosts.
It's fun, but can get unfair and frustrating at times, especially since you kind of need to have strong ranged and melee, (especially ranged) weapons by the end, and the RNG might not be feeling generous. Also, as far as I can tell, you can't quit mid-dungeon and start where you left off like the Binding of Issac, so if you quit game, it's back to the beginning.
Edit: oh yeah, one extra negative. Some of the enemy and boss attacks are just annoying, not challenging, not fun, not something that requires skill to evade, just annoying. Certain humanoid enemies can throw ranged attack, but they have so little warning and move as fact as your attacks, so they're nigh impossible to dodge unless you already are evading it, or you are expecting it. The obligatory spider boss shoots poison bombs that leave DoT gas clouds, but as long as you run away from it when it's shooting them, and stay away, it's pretty easy to not get hit, then just leaving it to tedious pot shots at the boss from afar. finally, and this thing is just awful, there's a blue blob creature that launches itself at you like a cannon. It blows up on contact, and destroys blocks. It's a pain to fight, and whether you can hit it with range depends on positioning and area layout.
Normality is a banality. Reality is a fallacy. Alter your perception, open your mind, and expand your world...with odd thoughts, eccentric beliefs, and an eldritch imagination.
