Hey dude or dudette! Welcome around!

I moved your post/topic to the relevant topic since it's some kind of introduction you did there (if you can, please try to take a look on the forums before creating a topic) ;)
Flop Rocket requires a certain amount of play time for most people to progress, but you can reach space once you're fully upgraded.
Quadropus Rampage is awesome indeed! That's what got me into the Bscotch community :3
Roid Rage is difficult but pretty fun in my opinion. It frustrates me in a good way.
Towelfight 2 is pretty easy (once you know the game). My advice: explosions and Area of Effect. Towelfight 1 is lost somewhere on the internet, it was an ooooooold jam game. With an actual towel involved.
Crashlands has difficulty levels. Challenge and insane are manageable once you have already played the game. The default mode, Adventure, should offer a good balance of difficulty (some hard parts, but not too many). If you fear that it'd be too hard, then there's an easy mode (I forgot the name).
Anyway, welcome around! ^^
