Thanks a lot!, having no box dropping from the mech should not happen, that may be because there are no weapons stored in the mech. Weapons have limited uses and you need to build them in order to use them. Maybe that was not clear enough in the tutorial, I'll fix that.
Also, you can research new weapons so you have more options besides the gun, maybe that was not clear in the tutorial either or there is a bug hehe, I'll fix that too.
For sure I'll add sounds and music :)
Thanks a lot for the feedback, If you have more I'll be happy to read it and keep it in mind :D
