Game is very lacking in balance once you get lots of health.
First the chance for weapon drops is almost non-existent, I got to level 8 twice with not a single weapon drop, you have to buy everything.
Other then that, doors are almost always useless (especially attack and gem demanding doors).
The only problem as far as I'm concerned is that cash doesn't scale well, it's tedious to get the amount of cash needed to advance.
Other then that the game is quite good (and funny)
A bit twitchy. But fun as hell, and just as hard. It' a good game overall, might do with some way to time the double jump so lagging doesn't kill your games, also it gets frustrating after a while, need a slow motion feature after a lot of failures or something.
The premise is nice, however the starting sequence is redundent, if you need to tell a story that has no interactivity, put it in a movie scene that can be skipped.
The controls are nice, if a bit strange, however the addition of the mouse at certain levels ruin the flow, especially since you demand both hands on the keyboard due to your key placement.
The levels are quite easy, and when they aren't, it's mostly because they are tedious, not because they are challanging.
Nice premise though. 3/5
Level 13 is rather screwed. The cat got so big that it simply had no chance of falling. As hypnotic as that was, it gets tiring after a 20 minutes.
Other then that the game is rather fun, and the movies are engaging.
