Really cool game!
Discovered a potential bug in the second level with book traps. You can bascially spawn books before starting the wave and those books will not disappear.
Besides that I only had a few issues with figuring out the tutorial text as the important ifos aren't highlighted and the font was a bit confusing to me. But that's a me problem.
Besides, when I got the hang of it the game was really fun and I would play more!
Played really well. Well done ^^
