Thanks for the detailed feedback! Your comment are most helpful as I'm still learning how to create strong narrative experiences.
Sorry about the slow frame rate, I guess 3D with post processing is rather demanding on hardware even with low-poly. Perhaps using lower quality settings might help?
As for the number of keys, I had originally planned for a longer plot with more gameplay and NPC interactions, but they got cut as I didn't have time. For now you only need the yellow (LV1) key to complete the game.
The drone is supposed to gradually build up more features and capabilities, but got cut due to lack of time as well.
Things you may not have tried or observed:
- you can tailgate the guards into restricted rooms even if you don't have the required keys
- you can take out guards to get their gun (which you can equip and use)
- passive NPCs will remember you when they see you doing violent action (punching others, using gun...) and will evade you.
I hope weave these into the plot eventually.
Thanks again for taking the time to play and for giving such a great feedback!
