Hello, can anyone help, or give advice ... How to implement the idea of a competition, the situation is such, there is a game, during the passage of which you get time, and I need to register it with the help of the mail, look it like this - went into the game - passed for the time being, the track got the result — clicked on the contest button — fulfilled the condition of leaving my mail, and now I need to save the mail data and time to an array somewhere when the condition is met. I tried to create through Google Sheet, but no matter how not responding. Are there any ideas how else to implement it, or if there are exact tutorials.

Time .... I take part in the competition .. mail

after that, the time and mail must be registered in the array, as well as a message will be sent to the mail stating that the person took part ... can this be done via google sheet, or should a hosting server be created where the data and feedback will go

Hello, I had a problem, I am a trainee in one company, and they gave me tasks to create a game (race), 2D, top view, with passing for a while, and then I created it, the next step. When you get the time for which you passed the track, you must complete a number of conditions, click on the button to take part in the competition, a window pops up where the player’s time is recorded and you need to enter the mail and agree to the terms, and the problem arose with how to save time, mail and player id in the array, as well as send him the mail that he took part ?
