Thanks a lot, glad you liked it!
It's true, I've seen almost every new player only stick to H2 and O2 for the first few games, and start to memorize more complex stuff as it comes with time.
My technical high score is 232, but there is an accidental exploit 100% intended game mechanic that basically allows you to go infinite ^^'
You did really well though, I only know 2 people that managed to get past 150 without cheating! (well, 3 now!)
