Yeah we noticed that. We tried to playtest as much as possible on the last day to avoid exploits but, to keep it playable for everyone and not make it too difficult, some sneaky strategies are still possible.
The grid movement and time only passing at each action definitely felt a little weird in the beginnig but once you get used to it they all make sense. Maybe a little too eerie since sometimes it is not immediate what is going on but overall a very solid game. Good job!
Nice one. For being your first game it has a lot of elements from sounds to lighting and it is quite complete, even though very simple. Good job, it was fun!
