Stressful game

I was having fun playing at first, but as I leveled up, there were so many obstacles like bombs that cause instant failure, spiders blocking the path, shrinking poison, and other disruptive items, all with a tight time limit. The frustration outweighs the sense of accomplishment from clearing stages. Watching an ad for a boost gives me an extra 10 seconds, and using an item also gives me an extra 10 seconds. It costs 800 gold (I think?) for 65 seconds (was it?), but gold doesn't accumulate easily, so it quickly becomes insufficient. I pushed myself to level 400 for a hidden quest, but it seems the rewards are lower than others, so I'm done with it.
