An option to skip the day would be useful, especially if you start with an awful launch. Also, the Hit Box is a bit misplaced, I was hit several times by items which I did not touch...
I think if you have a valid saved game of the original game, all endings should be unlocked, because not all of them can be selected. While I consider replaying it soon, I'd rather like to see how things could have ended in a different scenario.
After getting all Stars on Xtreme I headed to "Survival" with 4x lv.12 Megaplasma Canon (which tear down the last boss in ~20 secs). I reached the point where enemies were taking no damage... and I ended up collecting 500,000 coins.
LOL
When I started playing, I was not really convinced about this game. But after a (very) slow start, I am getting really into this. Wow, that's nice! I am just a bit disappointed by the expensive Upgrade costs. 4/5
The only way to keep tracking of the behaviors unlocked is to select "New Elder" (4th Scenario) and check what is unlocked and what is missing from DontClickOnMe's post. Overall, nice game!
