Spirit City: Lofi Sessions is an amazing productivity game that mixes your customizable avatar with productivity tools that help you focus on your tasks.

You can customize your avatar, room and choose your pets. Gives you a lot of lofi chill songs to listen as well as adding some sound effects like wind or keyboard noises to help you focus.
Each of the pet spirits that you find gets added have their unique entries in your catalog that teach you more about them and which tasks you need to do to find them.
It has a lot of productivity tools to help you in real life tasks, such as the pomodoro technique, journals, daily checks and tasks list.
They update the game often with unique things, some that follow the seasons that we are going through like Fall or Winter and also themed ones like the Halloween update!

This helped me a lot to get back into action, get on track with my health and even finish my graduate course, so I highly recommend it!
