I played through the game mainly for the story. I understand that this is aimed at a more puzzly audience (I enjoy puzzles only for a certain period of time) but still I have to say I got a bit bored and frustrated that I can't solve a certain puzzle (I'm looking at you swamp) because I'm tired and lack timing. On the other hand, I can't say I did not enjoy it :)
Tisk, in my opinion it's pretty generic, also teammates harm your team more than they help it, and that ultimately ruined the game for me (esp. lvl 14 from aliens). The game is poorly optimized even though it's graphics aren't spectacular (I have pretty decent rig, yet it lags constantly. The last level would not load for me, thus leading to more frustration. It had it's pretty awesome universe, but everything was ruined due to poor execution. I'm sorry, but that's just the way it is.
It does show the potential unity has, but first of all it's a draft. Don't downrate my comment for saying the obvious. I'd like to see a true game by you.
the game has immense potential, but you should fix the popup instructions (unless they're broken on purpose) and some things like 'XXX meters walke' or the band covering the 'next level' button
The most important thing lacking in this game are hovering pop-ups that explain statistics. I don't have time, or will power, or a strong memory, so I don't go to the library to check on whatever I think of in combat.
