Found a few issues
1. Stuff going through walls
2. Amount of money is not enough to step up the game (in terms of affording higher quality ingots and such) - just increasing the amount a bit may solve it.
3. Customer timer - at day 13, they come in and they immediately leave. Lower the amount of seconds lost each day, or better, make it so depending on customers mood, the amount of time will be different, but enough for the player to make a weapon.
4. Customer leaving at night - the last customer should stay until weapon given or time out after night comes, without leaving.
That's about it :) I really love this game, been playing it nonstop all day :D :D So I hope these things will be fixed, especially those customers :D :D
