Some bugs/glitches/oversights I've found:

If you touch the lava after switching, the level doesn't end. On reentering the character, if they are still in lava, the level ends.

If you jump into and hold against the other character, you can surf them

You can switch character and fire arrows during the level end and game over screens. The wall also continues to move, until it reaches your character

If you jump against a wall or door, you can keep some height, and surf along it for a bit.

You can stand in windows, which would let you skip activating the button in the first lava room, if you could jump off the platform with the bow (wall surfing doesn't give enough height).

You can press buttons repeatedly, which causes an earthquake

Players can stand on opposite colored buttons and still clear the level

You can right click the buttons on the game over screen. I have accidentally exited to main menu too many times because of this

Edit for additional:

If a character picks up a bow while in the transition animation, it appears in the other character's hands

Characters can hit buttons while not active

You don't have to look at buttons to press them

Nice job Barji! A very fun challenge. I like how you need to keep moving forward/carry your momentum while switching to beat the wall behind you. The nature of the gameplay turned it into a speedrunning game on it's own it seems :D Great work!

Cool mechanic. Couldn't get passed 2nd level, did anyone else?

Never mind, beat it. Wow! Precision, timing, understanding better the level, does this happen by accident? I would think not. Good work!

Frustrating, challenging, rewarding

The game was presented amazingly! It might just be my computer but it was pretty low fps. Althuogh without that in mind, this game could definitely be a well polished game. And in my opinion I think this should get in the top 100 games. Great game!

I feel it was a bit to punishing (tho it seems you intended it?) I like the concept. Also, I don't know if you wanted it to be that way but the framerate wasn't cap and my computer decided to burn while I was playing, super smooth tho jaja.

I liked the game! The graphics were really good, but as others have said the bow was hard to shoot at first, took some time to get used to it (a small reticle in the middle would've helped to guide me). The concept is great and it's executed well here, and the walls pushing in was a great way to add more intensity! Sometimes I felt I slid to far when changing positions but I got quickly used to stopping before teleporting (and sometimes even using the slide to an advantage). Great game for 48h and the teleport effect was epic!

I like the game idea. But the bow is hard to shoot. Also, I think there should be a reset button. I went to the blue and red buttons with the bow and shot it and it did not restart the game so I had to close the game and open it again.
