The app works great, however... when it comes to the licenses... They have two big issues that simply cannot be overlooked and can waste people a LOT OF time or even cause people to want to refund it.
If this is ever fixed I'll update my review to be positive, but for now... here's some workarounds:

1. Remove Gamemaker from your library
   
2. Buy the license and install Gamemaker again
   
3. Make sure to login to properly have your license

So this info below is no longer needed, but leaving it just in case:

1. Log off from your Gamemaker account
   
2. Log in again and it will be fixed

play alone simulator because it has better content than the single player version

*Abusing Co-op features since it ever became a thing*

very fun online game about 2 kings/queen that fight off crown stealers while being forced to build an empire from scratch with nothing but coins and random hobos from the forest

Angry person beats up demons that haunted him from the past and then continues to cause mayhem to save his planet and humans

very fun platformer with run and gun mechanics

With 69 hours into the game (on this account)

I can happily say again

This game is called WarFarm not Warframe.

Anime workshop simulator

Can't wait for the Source 2 version with even more anime mods. :)

Remember to take out your knife to run faster.

Because apparently having guns in your back instead of holding them makes them light as a feather.
