A wonderful entry that really got me stuck into. Great realisation as for just a week game jam. But lemme get to some criticism :)
Theme:
I like that you've touched the theme in several different aspects: plotwise (factories influence on planet), gameplay wise (removing factories has some influence on what's happening in the game) and prob even more that I would need to think about :)
Visuals:
Oh you did a great job as always, maybe even better this time. I love how you tried much more detailed attempt this time which gave a really professional effect. Game is really well juiced (loved that explosion sound and particles on button interaction :P) as everything here is interactable, background is alive (those little people wandering around, clouds making a beautiful landscape). Really hard to point anything out. If I were to advice anything, maybe it would be a nice idea to change color pallete at the ending a bit to sth more natural/clean (green/blueish etc maybe with some parts of orange you did earlier, to indicate that even tho we cleared up factories there is still some influence it did to the world) to indicate that we really helped the world by destroying those factories.
Innovation:
I've loved the idea with the cards and that's something I have never seen before. Mostly in card games, your cards have an influence on something else, like an object on map etc or enemies cards, but I don't really remember any game that makes you actually manage your own deck and destroy it :P
It's a solid game for steam, especially that it just needs more content and maybe some more complex opening/ending to be a proper steam game (apart from that, perfect).
SFX:
Sounds are very clean and well fit (as mentioned before, I just love that explosion sound :P), music is great, but I suppose it would be good if it differed on different parts of the game, especially with story telling (starting depressingly, playing with what you provided (sad, but motivational) and end up with calmer, but slightly positive, or sth like that). Different music for opening, game itself and definitely ending (no music change here gives no feedback to player, like I didnt really feel like I did something), ofc I know that it's a game jam game so it's not easy to fit all of that during that time period, just trying to point out some things that might be helpful if you were trying to work on it later on ;)
Gameplay:
Truly enjoyable, well introduced (love the hints that you gave, beautifully done), amount of levels is perfect for game jam (would need much more for steam tho. Would be good if they could be in like separate bioms, as it could give some more artistic variation (winter, desert, this biom etc). As I suppose that at that point entire planet is covered with factories :P ).
I love the fact that it's really creative and requires a lot of creativity from you (you can beat some levels in different ways).
Difficulty level is almost perfect, game isn't too hard till several last levels (lvl5 and last were tricky for me), but they are possible and game got me into enough that I've beaten it to the end (which doesn't happen quite often on gamejams).
Design:
You did that wonderfully. Leading the player enoughly to understand all the mechanics and leaving a lot of space for creativity, that's not really easy to do. Also game really feels like it's living and that;s also very important. Maybe just plot-wise it would be good to work a bit on, but apart from that - jam masterpiece!
Thank you for creating it and giving me a lot of joy playing!
Keep up the amazing work.
PS: Oh and I missed the 'Back' button on last level when I were to build those factories. Had to restart level several times because I couldn't go back :P
