I like the concept of this game, but it's too short for now.
Maybe some stronger monsters planned?
Otherwise, I'd like to see some paths, I mean some monsters that you can't fight if you decide to fight another, depending on the bonuses you're wanting.
Nice game, but boring at a moment, it would be interesting to buy a same square man multiple times (or to be able to mix some abilities). For example buying multiple anti monsters would be very useful, and mixing it with underpass even better. I mean, having all bots being stupid at first then specializing them as they eat.
Yes, only one type of wood. True originally intended more, but there have been some difficulties :(
