I've really enjoyed what I have played of season one so far, but here's what I would like to see changed in season two:
1) It seems the splash screen that comes up when you double click a season has no option but to launch the game. This is annoying if you accidentally open the icon, or like in my case this morning: I saw that my download of episode six was done, and I proceeded to install it while checking my mail before work. After it was done installing, that splash screen came up to launch the game. Since I couldn't close it, I figured I'd just launch the game and then quit. Unfortunately, I was also forced to watch the entire opening sequence before I could quit. It tacked on about an extra ten minutes to what I was doing. A simple 'x' close button in the corner would be appreciated for when that splash screen comes up and I don't want to play right that minute.
2) Having six different icons for each season clutters things up. I'd like to see a single "Sam and Max" launcher, and then I either pick which episode I want from an in-game menu, or from a unified splash screen to replace the one that each episode currently has (which will have an 'x' close button, right?). :p
3) Sam and Max apparently does not support wide screen resolutions. With wide screen laptops being so popular, and wide screen LCDs becoming more and more prevalent on desktops, I hope that season two supports wide screen resolutions. I don't really care about the cut scenes taking up the whole screen (I know a lot of that is direction and 'framing'), but it feels silly to have to click twenty times to get Sam in front of Bosco's when I have two inches of blank screen that could cut the clicks in half. Which brings me to my final wish:
4) Click & hold movement. This really seems to be an annoyance only on the wide, scrolling areas in the game. But as I said in point three, it's annoying to click a bunch. Especially when I walk up to Bosco's and accidentally hit the gumball machine. Then of course Sam comments on it's contents... again.
Season one has been great, I'm really looking forward to the sixth episode. I'll likely buy season two reguardless, but changing the above points I think would make me (and I imagine quite few other people) enjoy the experience even more.
