I'm using window mode. space and reset arent working

I see there was Demo launched at August 3rd but can't find it

I don`t understand this game. There is no tutorial, how I can decide which can I will get???

I can't find a way to place my monsters so that the requirements are met and fit into the 8x4 board.

The leaderboard is not loading in on some levels, and I can't reload my best solutions on the levels this is happening on. Even stranger is sometimes it will load the monster count stats but not the speed or tile stats for a level. Also what leaderboards will load will change if I exit steam and then start it again. But it will never change if I just exit out of the game and turn it back on....
