Many MANY hours later I have finally finished this game. And it's still fun to mess with. The concept wasn't original but the mechanics were definitely fun and the levels overall were a decent level of challenge (but THAT LAST LEVEL CMON) I'd definitely be interested in seeing more levels though, it was fun. A few finer points:
- Early on the "positive" character felt like it had easier areas than the "negative" character. So I feel like some balancing there would help. Or you could lean into it and vary it up with negative focused levels and positive focused levels etc.
- The "negative" characters gravity kinda threw me off, but it did end up being helpful for getting through some more specific areas meant for him. Which was nice. So I feel like tweaking it only a bit would be nice, not sure exactly how though.
- Difficulty curve was a bit weird sometimes... so tweaking that as well would be nice. But overall, a really polished level design, a near rage inducing last level and a fun overall experience.
If you get more levels, I'll definitely play them. It was really fun to mess with.
