Hey mate! Thanks for playing my game, I really appreciate the feedback and I totally agree with you.
I still have a lot of different ideas for missions, like delivering a bomb to the enemy facilities, capturing the leader of enemies as a "package", hiding keys to open doors and capturing packages in houses, but unfortunately I ran out of time to implement them, it was the first time I set up an AI with enemies and it took me a bit longer than expected. But, I am planning to finish the game with more game mechanics and levels and try to pushing it to AppLab on the Quest :)
