early acces game with achievements = a red flag

Achievements are based off of a completed work, knowing everything in your game and then rewarding people for various actions. If you have an Achievement system in Alpha, from experience, it means you have no intention on finishing the product as so many i've opted into that did, have done that.

Chill. Achievements usually come late beta.
