Happy to hear from you again! And really surprised you got 40 plays! That is a good amount of boost!
I have noticed that your gameplay video on my YouTube did good too for the last 10 games I have played on itch.io (at least 10 last games, it might be more) and your 16 minutes video has been watched for 1.5 hours (which is good comparing to typical watch time this week) All of this is honestly to your game being good and interesting to play! So if you are satisfied by the your boost you should know it is all due to your game being good ;)
For the cheat codes! it is really up to you! It is just a personal opinion here lol (you should get more feedback on that before doing anything I would say).
