Okay, the little bubbles on level three are just ridiculous. Trying to focus on the pattern well enough to click through with skills kept inducing seizures. Sorry.
I hit 100k at 75 combos in a row. Lag was my friend. Suddenly made everything a LOT easier. If there's a sequel to this, definitely mute button and reset button.
Another time server for level 3. you don't lose any time for warping back to a checkpoint and all your oxygen is renewed. Also, its much faster to jump up a hill than run up one. Contrariwise, I 'think' its faster to run DOWN a hill than jump down a hill. Final tip: when you are going down the long hill from oxygen point to oxygen point, if you hit spacebar at the 2nd checkpoint in the game, you won't need to stop for oxygen till the 3rd checkpoint, where you hit space again. Finished level 3 in 199.
Something that I didn't figure out till almost the end. RIGHT CLICK to change performance settings. That took a lot of the irritation off the game and would have been nice to know from level 1. I don't recall seeing that note anywhere.
