I always love Nerdook games. This one is included. I just felt it was a little too short. If upgrades were to carry over I would definitely feel a little more incentive to play through on the harder difficulties. Hella fun though. I would love to see what Nerdook could do with a straight-up RPG. These ones that are always a mini-RPG with a twist are great, don't get me wrong. I just think Nerdook could do a lot of cool stuff with an full-blown RPG. Thanks for a another great game though homey.
