Pros:
- Good graphic
- Nice story as background
- Geeky physic humor
- Fluid and responsive controls

Cons:
- Control point system which forces player to run through big chunks of already beaten areas after restarting game

Conclusion:

I really like this game. For science background and bad physical puns found in journals, and this feeling of lightness when I ran around. I have dreams like that, when I don't quite fly. Just feel like gravity doesn't hold me down, so I can jump around really high and really far. And this game nailed this feeling.

Apart from that game has nice story that's set up during times of Manhattan Project, nicely designed maps, and abilities that are unlocked during gameplay and give feeling of nice progression

Pros:
- Quite a lot of background objects to destroy
- Sword fighting system that I liked 10 yearts ago
- Simple RPG level up / ability system

Cons:
- Inability to use alt+TAB without bringing up main menu
- Most weapons are ineffective for some enemies, so only viable way to kill them is... kicking them on spikes or off the ledge
- Maps are small, but sometimes it's possible to not notice this one jump place needed to progress game further
- As always bows and magic are inferior to swords

Conclusion:

This game dated xD I played it when I was teen, and bought it during this steam sale to beat it again. Combat didn't give me this "wow" impression like it did all those years ago. Also simple things like shooting ropes to reach higher places or ability to destroy barrels wasn't so amazing as it was 10 years ago. Because then it felt as something fresh and innovative in comparison to other action games I played.

Still I liked it. Not because it's good game, but because I liked it when I played it for first time. So nostalgia, not actual gameplay.

Pros:
- Different characters play different role at party
- Diverse set of abilities to choose from
- Advanced hero creation system
- Ability to beat whole game in co-op

Cons:
- Lack of voting system in co-op part and overall bad implementation of co-op module
- Bland companions
- Broken quest marks
- Badly designed journal and shop system
- Not memorable story

Conclusion:

It was yes and no experience. Ability to beat whole game in co-op is nice. But implementation of co-op module is bad. Only host can pick up dialogue options. It's impossible to share inventory or do shopping at the same time as co-op player (when 2nd player click on merchant, 1st is kicked out from shop menu). It's impossible to use client player stats (like charisma or intelligence) to get pass conversation prompts, only host stats are checked.

Game also suffers from bugs. Like broken quest markers, getting stuck in conversation boxes, or just getting stuck in some action when co-op partner decides to click on something. And it requires game restart.

Roles at party are diverse, someone need to walk around and detect traps and disarm them + do lock picking, other NPC need to play as tank, and others as DPS. So game is diverse here. Still NPCs that are in party aggro enemies way too much. Also enemies can get stuck in some place (esp those huge jelly cubes) which makes killing them ridiculously easy.

Overall it's not good game. You can't also buy it now on Steam, as it was removed from shop. But you can play it in co-op and enjoy it. I don't think I'd want to beat it in single player though.
