This game gave really chill vibes. The colliders and controls in general could use a bit of polish. The idea was very neat tho.

This is the best use of limitation I've seen so far. I really like the idea of having only 10 seconds to control certain character, but lack of polishing makes experience so much different. I'm not sure why you've submited 14 hours, 12 minutes before the deadline (I guess there were some other important things?).
If you want to improve the game this might be helpful:
- Platformer toolkit by GMTK game jam
- SFXR, BFXR or existing assets for sound effects (you can change pitch to make sounds feel less repeatative
- Add timer and corresponding effects (like tickingthat is get more intence as timer approaches 10 seconds) to indicate how much time is left before switching players
- Maybe add unique ability to each character. For example one jumps higher and moves faster, but other one can move objects around (just an example, you can experiment with your own)

Anyway good luck with your future projects. This sumbition has great concept, but lacks execution... :D

Fist of all, good job! Second, we feel some some imprevements could be made to this game. Having acceleration doesnt work quite well with plataformers, and the switching mechanic can be a bit annoying to wait the full 10 seconds. Despite this, the use of limitation was creative. Very nice!

nice concept

I like the idea.
That's a really creative way to implement the limitation.
Also the graphics and music fit pretty well.

The game had a good look and soundtrack, and it's great that you made a game in 3 days all alone! I really liked the walljump mechanic and the level design.

Some feedback: 

• Rebind the restart key to R or Q: Space is usually jump in platformers and my reflexes kept restarting the game trying to jump ;)
• Try reworking the colliders: it was really hard to get on top of the stone player (if that was the right plan) as the game kept pushing me off
• Give better instructions: it took me a while to figure out that the green dude could walljump and the blue one couldn't. Also, the conveyor belts should be animated as I thought I was getting stuck in the wall
• A timer for the switch

Keep at it and improve this game further after the jam ends.
