Known bug: If you reach the level 16 without using passwords, the game will crash after the level 15 with message "File not found". Workaround: write down the password of floor 15, reset the game, choose "Password", input the password and now beat the stage 15. Map 16 should load normally now.

A nice little challenging game. I played the first couple of levels and even got it working full screen. Totally reminds of the REPTON days from the BBC Model B.

Thanks DEVS

Great game. I think it about an hour to beat. Thanks!
