Round Two. Fight!
Next round of themes. To be honest, I liked round 1 better, but there are still good ones.

Keep the light on [0]: It’s OK, but not much possibility for humor, which is essential for LD.
Explore [-1]: Too vague and seemingly content-based. And there’s just no time for quality content.
Castle [0]: Not too restricting, not too broad. Can give both mechanical and aesthetical ideas.
Keep it contained [-1]: Seen it, done it, don’t wanna do it again.
Roots [-1]: There are two routes to take, and both are pretty restrictive, so games would be too similar.
Treasure hunt [0]: Don’t mind it, can be done in very different genres. Good.
Piracy [+1]: I love pirates. That’s enough of a reason.
Sacrifice [-1]: Again, our usual contender. Let it go.
Garden [0]: It’s fine. I think.
Single use [-1]: That’s just bad for the environment.
Power source [0]: Might be fun, might be a nightmare.
It spreads [-1]: It doesn’t.
Strength in numbers [0]: Very similar to ‘Stronger Together’, but I mind it less.
Strange machines [-1]: Feels like a lot of art with no time for art.
Mutation [-1]: Cool theme, not for 48 hours.
Summoning [0]: It’s OK. Doesn’t make me go ‘I have a brilliant idea!!!’, but it’s OK.

I really liked the game i done for the compo and decided to continue the work on the game for a future version.
For now im preparing a bugfix for minor issues (final score calculation at the end of the levels and a bug allowing summon creature closer then it should be) but will leave the compo version untouched.
