HyperRogue

You are a lone outsider in a strange, non-Euclidean world. As a Rogue, your goal

is to collect as many treasures as possible. However, collecting treasures

attracts dangerous monsters (on the other hand, killing the monsters allows more

treasures to be generated).

You can kill most monsters by moving into them. Similarly, if the monster was

next to you at the end of your turn, it would kill you. The game protects you

from getting yourself killed accidentally by ignoring moves which lead to

instant death (similar to the check rule from Chess).
