Okay, fire rune. I'll list some of my favourites here.

One that I personally like a lot is The Glassworks. You may just find the big challenge on the very last levels, but it's a matter of agility on the keyboard. No puzzles will wait you there and early levels are a piece of caek, but two-sided-jumping-and-tapping can be very tricky and it may require timing in later levels.

A good choice is also Rubble Trouble series. You've already completed Rubble Trouble Moscow, so nothing much different will wait you in the prequels, but some levels may require a bit of contemplation before you go and bomb everything on your way, especially when that pesky Larry is there. A fun physic challenge awaits you there.

Now this is more like a challenge -- Super Treadmill. You have to think fast there, and the best of the game is that it requires failure. You may need to see how a level is going to build so you can get further without surprises.

The Trap series are fun, but not terribly hard. At some points the traps starts getting ridiculous (especially in Office Trap), but it's very fun to play such a funny trap-based platformer, since it's a funny and addicting gameplay.
