I played through all the levels in this game, I take it this was inspired by fireboy and watergirl.
Positives:
1. The levels are pretty well designed
2. Can be enjoyed either be yourself or with a friend.
3. Browser Playable
4. The levels design is pretty good
Negatives:
1. Missing out on most of the things that were initially planned.
2. I'm not a big fan of the delay of moving onto the next level, it confused me on the first level. Maybe this can be fixed by adding a transition
3. The entire screen moves when you move the blue character, I think this problem is from a setting you turned on with your itch.io project.
4. Doesn't really have an original idea, maybe this is just because your using AI and are just trying to start off as a game dev, but this is really important in the gaming industry especially with the rise of AI.
Overall a 6.5/10, I bet just another 3 days of working on this would bring this to an 8.5/10
