I'll try not to bore you to death by repeating what everyone has already said 😅
I will say this, though: I did think the concept was super interesting. The way you made that "Thoughts" window was very intriguing and I felt like this could have some really deep gameplay! The goal WAS clear - kill them both at the same time - but I was unsure how to achieve it, especially with the gameplay elements that took me a while to figure out - such as not being able to move the broken block with the blue knight, being able to fix the platform with the blue knight and break it with the pink, etc.
Regardless - I was determined to understand everything and beat it - so I kept trying for a while, and... I did??
Thing is - I'm REALLY not sure how I managed to do it 😅 All I did was:
1. Fix the platform with the blue knight
2. Go up the platform with the pink knight
3. As the pink knight, drop the broken block on the platform (which sometimes fixes it)
4. Jump off with the pink knight
and... win? And it consistently works - I did it 4 times consecutively, haha. One time it didn't work instantly, but then DID work once I entered the pink tunnel with the blue knight?
A little confused but uh hey at least I escaped haha.
Anyways - I think the mechanic is solid, there's clearly a good idea here - it's just the gameplay elements that confused me a little bit with the different interactions and their visual language. I hope you do continue to work on it and improve it - and I wish you the best in your game development journey! :D
