Luckily, all of the puzzles are extremely easy, requiring only a few second's thought, even on the first play through! Those aliens must think we're amazing, if this is the metric they use - we're all super-geniuses!
In this game, you are penalized in later stages by increasing cost of purchases coupled with a longer (worse) snake, and powerups not carrying over. If you mistakenly bought upgrades early on, you're screwed later and there isn't any way within the game itself to correct that mistake by resetting your save. The only way to make that credit back up is to grind, which is mindnumbingly slow at 100 credits each playthrough of a level on a difficulty you've defeated before, and the higher levels aren't winnable without upgrading... which defeats the purpose of completing them for credits on harder (further temple) levels.
Playing witch.. The lower level maledictions are pretty damn pointless. Lower stats... by 5%. Which does nothing to any (but 1) of the mobs I've met so far, none of them have stats at 20+! Shouldn't these be changed to always do at least 1?
I don't know, I didn't particularly like it. For the classic puzzle game setup, there were no puzzles worth mentioning. For a psychological tilt, it wasn't engaging enough to make it feel like it was actually insulting or demeaning. If the object was more development on the part of the computer/entity realizing that it could have hatred and some inherent conflict there, it was far too abrupt to be convincing or meaningful to me, one second the computer was yelling, and suddnly "oh, wait.. I was wrong, goodbye."
I like it. simple... there IS NO HP... kinda obvious puzzles once you get the idea.. very beautiful.. only thing is its a little empty... perhaps more planets and an objective in space
