Its good, that you set yourself a deadline.
I think, the problem with teaching the damage could be solved by showing the damage you do. Like Borderlands or Dead Island do it. Then you have both the finding out and you have the learning, that its more effective.
Meele is also thing. After writing the comment, I actually realised there is meele… But I haven’t noticed, because I jumped right into the game. But meele doesn’t feel right. You hit multiple time a enemy, but “nothing” happens. What could be improved by giving a time window where you instantly kill the enemy. f.E. Shoot down to 20 health and then meele. Similar how DOOM does it.
It has a goal? Good. Then next time maybe make it more ovious. :)
Audacity has a Checkbox when changing Bass and Highs, where it automaticly adjusts the volume.
And no I don’t expect you “fix” or change it now. Its just feedback, how to make it better next time. :)
