Cool concept! I like the physics-based gameplay and the chemistry theming. Not being able to stop in the walls adds an interesting wrinkle as well. Would be cool to see this expanded with more levels and obstacles. One thing that could be a nice addition is some indicator of where the oxygen atom is relative to you. On some of the later levels I wasn't sure where to go at first.

Pretty nice physics game! If you are going to make this a long-term project, here are some comments I have for you.

Some context about my playthrough: Beat the game, failed a level a couple of times.

What you did well:

Theme was incorporated well, I'm very glad I saw this one because I don't think I've seen anything like this in the jam.

Moving around in the air feels smooth and fun especially when my momentum transfers.

Pretty cool concept of using elements and trying to bond with others.

Suggestions:

Speaking of elements, you can add interactions that don't involve just winning. Things like palladium would make your character gravitate towards it a little bit since that's how it acts towards hydrogen in nature.

The game in general requires polish for a more long-term build like sound effects and cleaner visuals but I'm sure you're aware of that already.

If you make more levels, I honestly had the most fun with open levels where I can launch myself around so consider adding more open levels!

It feels like you can play the game with only 1 control (either A or D). I basically only used 1 letter the whole time. This isn't necessarily a problem but it does make the controls feel a bit redundant. There are a ton of random ways you could fix this, maybe giving each node individual energy or giving them different effects etc.

Something about this game makes me think it has a lot of potential. I think you did well given the time constraints as well. Good work!

simple yet fun concept! also very well-balanced difficulty, as making it to the end wasn't easy, but wasn't overly frustrating either. well done :D

yooo pretty conept, i've pretty like it, at the beginning a was like "what ?, not arts ?" but now i see the potential, keep going bro, congratulation, and btw my game too is based on changeDirection rotation, let tceck ( plz?  ) 

Who knew I would like making water by spinning hydrogen molecules around. I love flying mechanic as well. This is the new and improved science class. Only recommendation I have is to bind a to one and d to the other versus based off position bc when spinning it becomes rng.

Had a fun time playing this!

The movement was a tad confusing at first but once I realized I was launching the hydrogen I enjoyed the momentum and the sort of "spin-and-go" feeling I could create as I navigated the levels. Losing when you stop spinning when a hydrogen was in the wall was a bit confusing as well, but that became clearer with your game instructions and easier to deal with once I knew how to move.

The levels were fun!

I really enjoyed the music, props to the composer.

Well done on making your game!

Very enjoyable game! The movement took some getting used to but really enjoyed it!

I got very absorbed while playing and didn’t even realize when the levels looped back to level 1. Even though the visuals are simple, the movement and level design are really enjoyable and fun to play through.
