Hey I don't see the game in the itch.io game mmmm.
Give a try to our game Terminal Travel if you want! Thanks :)
Yeah it works!Funny game ahahah
Here some suggestions from my neewbie experience:
Remove the collider from the coins
Increase the cropping plane of the camera, right now when you jump you can go inside terrain visually
Make it a little brighter, the game seems to dark in some spots that you can barely see
Bye!
