100% solid gameplay. The difficulty curve, the mechanics, even like the spacing of the bugs and how that keeps the player on constant alert, was handled perfectly. The music and sound effects were perfect, adding to the mood without being distracting. The graphics also were wonderful! And I will concur that I loved the day/night mechanic and how it kept stakes up and visuals interesting.
No notes or suggestions! Everything is really well done. My high score was 2900 but I think I might play some more to try and get that up. I had a ton of fun with it!
