Is there any way to disable the hotkeys bar banner at the bottom? Have a playthrough on mobile phone chrome browser right now, and it's playable for the most part, but that banner cuts off the bottom 20% of the screen and makes some things impossible to click.

I swear I played this a long time ago but I don't remember where. Guess I'll restart it was fun.

This was one of the better ones I've played, just wish it went a little further in depth. Albeit, it does take a while to get to the "end" of the game. You essentially get to a point where there's no more progress and gain resources forever to no end. The part I liked most was that you get to replay the game due to a mechanic and it can be vastly different depending on your choices.

Arcanum has always been one of my favorite RPG focused incremental games. There's really nothing out there that offers anything quite like it in the genre, things come close but ultimately have different appeals from Arcanum. So I'd like to thank Lemur, Mathias, Mindedness, and the others that have worked on and maintained this game. 5/5

I've loved this game for a long time; arcanum / ToM is a rare type of RPG that I wish there was more of. It's really great to see that it's coming to a more accessible location for new players to find. It's a bit of a shame that it isn't being actively developed anymore, because it has so much potential, but the game as it exists today is still a very fun way to spend a few days so it'll always be something that I recommend to others.
