Driftin is an incredibly addictive lap racer/battle game, you have over 6 types of racer to pick from that all perform better in certain aspects, for example some may be faster but have lower health. Most of the vehicles also come with a special ability which can assist your playstyle too just remember as fun as it it to blow other people up the winner is crowned as the first to 20 laps!
As previously mentioned your main goal in Driftin.io is to get to 20 laps completed before anyone else, every lap will give you a level up which will allow you to upgrade one of at least 4 stats these include max hp, hp regen, movement speed, weapon damage (If you have a weapon) and reload speed (again if you have a weapon). Some people choose to level their stats so that they can kill people and take more hits, others choose to go for a faster alternative that can avoid combat and get the laps done, there is no 'best' way to play so play however is entertaining for you!
Your vehicle will go forward in whatever direction your mouse cursor is, to use your special ability simply use the space bar and left click to boost your speed for a limited amount of time.
