The idea is cool, but there’s still a lot that could be improved. For example:
- Add the ability to unlock new office rooms.
- Improve the destruction physics.
- Add some fun office-style background music.
- Make the game’s tutorial/guidelines clearer.
- The gun isn’t very good at picking up objects — take inspiration from the Gravity Gun in Garry’s Mod.
- Add some lore and motivation. For example, maybe you got fired and decided to come back late at night to trash the office, or something along those lines. It would give the player a reason for what they’re doing.
These are just the things that stood out to me right away. You should also think about what else could be improved to make this a game people would want to play for hours.
Good luck! I hope everything works out. 4/5 for now, with the expectation that you’ll keep improving the game and polish it to the point where you’d be proud to show it to your friends.
