This game would be more fun if:
1) skip dialogue
2) if you accidently get a choice option, you can quit to not make a choice
3) i there wasn't bugs with leaving 'sticker wall'
4) if there was another passcode quest taht doesen't involve 'hole'
5) if there were more dialogue options with your colleuge, just simple talk? woud make game a little bit more replayable
6) if there were number of endings and how many you've already got or just a progress meter in percents
7) last but not least the last ending erases all the progress, it's inconvinient if you want to get all endings
Also, a second part would be great! Good luck! Hope this comment is helpful
