That's one tough last boss. I thought it was impossible until I watched for the exact second to jump. I've never been one for this style of game, and it's not easy by any means, but it's still a pretty darn good game. 4/5
I don't know where you bought your watch, but it displays quarter seconds as full seconds apparently. I doubt that shield lasted a full second, much less three.
Use your own graphics and there wouldn't really be a problem with the game as long as you make it clear it's a basic puzzle. May want to increase the difficulty, as one almost has to try to get a wrong move.
I'm not sure if the Death Mask isn't working like it should or if it's written description is wrong. Instead of dying at the end of next turn, as the text says, the character dies during that turn if they are killed before the end.
Really don't like the amount of time given to make a choice. If you get slow rolled by an immature opponent that wants to piss you off they can do it pretty well. And a sixty unit (didn't really feel like seconds, sure as hell hope it isn't a full minute) countdown is very, very long. Thirty would be far better.
Seems pretty luck based. Maybe if the size of the window were expanded so that you know what's coming and aren't tricked into making a move that's literally impossible to recover from. Good engine, though. 3/5
Wait, there really is a mute button, it just only temporarily stops sound only when you hit it and then the sounds starts as soon as you aren't watching? Wild. Sucks like nothing I can describe, but still...
