Snake vs Block Online

It's super fun to navigate the terrain, which is interspersed with numbers, some of which add to your lives and some of which deduct. The lives are arranged like a snake, showing the total number of lives on its head. Each selected block that is not placed in the batch of 5 in a row, can be added to or deducted from your lives. The most global task here is not to face any block that beats you with its number: everything you pass will be less than the number of your lives by at least one. Let's say your snake has 20 lives now, so in order to pass, it has to dig through 19 or less. Don't forget to collect all the numbers that add lives and avoid the ones that remain, choosing the excavation sites intelligently so that your path is as long as possible.
