Two observation modes are available for now (as explained and coded by Hamilton et al. 2014):

• Sparse scalar observation (Binary number 0-2^16-1), some bits zeroed out
• Sparse observation vector (16 bits), some bits zeroed out
• Full scalar observation (Binary number 0-2^16-1)
• Full observation vector (16 bits)
• Fully observable ASCII (21 x 19 str)
• Fully observable RGB tensor of (21 x 19 x 3 uint8)
