Although you can use the in-game cash you earn to continue the game when you get killed it is more beneficial to save it for the entire game upgrade. A better way to continue the game is by watching the adverts when the option presents itself.
In-Game Cash
If you spend the in-game cash you earn on the entire game upgrade you will get monsters and score multipliers that will improve your score dramatically.
Obstacles
Remember to make your character glide over obstacles like spikes or buzzsaws by holding the left or right part of the screen.
Random
Don't bother trying to memorise any paths or strategies as the games are all completely random, you just have to let your intuition make the decisions.
Various Tips
Don't forget to hold left or right part of the screen to make your character glide over obstacles like spikes or buzzsaws.
Spending in-game cash is a great way to improve your experience. One of such ways is the entire game upgrade that gives you both new monsters and new score multipliers that improve your score dramatically.
You can also use your currency to continue the game when you get killed, though it is probably best not to use it too often.
Another way you can continue the game after dying is through watching ads. You don’t always get this option, but when you do, use it because it is fairly harmless.
Since all games are random, there is no need to memorize the paths or strategies. Simply go with the flow and let your hands do the work.
