I believe you're absolutely right, thanks for the extensive review. If this game had to go further, it should definetly go multiplayer. There's also many other things the game obviously needs, and would be attended to in the future If I decide to pick up this prototype for anything serious.
The artist made the rooms modular, and we had planned opening further rooms, maybe as the game progressed (that's probably why I didn't care much about the game's progression at the begining but ended up accelerating it substantially relative to how the initial release was a few days ago).
Anyway, this was a fun project that got me refreshed in Unity, but I'll be doing something more long term and serious from here on.
This doesn't mean I'm abandoning Bricks Room, it's a jam project made for the experience, but will be polished as much as the reviews
request it. If we find any game breaking glitches they will be fixed (I think there's some issues with the doors still :P).
