I vastly appreciate this in-depth review and I have actually been working with a lot of these issues you have mentioned. Out of all the problems you've listed, I feel as though the most urgent is the lack of proper onboarding and I have been revamping the first two levels to give more practice time for later levels. The rope is by-far the most complex and basically useless feature in the game, so i really need to set up a dedicated tutorial for it. I think I may change some of the rope's functionality to make it less confusing/janky in the future. Thank you for playing my game!:) Edit: I forgot to mention that the touch grass button and tweener errors are mostly due to the game not originally being built for browsers; the existence of the web version is so that more people will play it in this early access state, as people generally are more willing to play browser games on here. The touch grass button closes the game in the non-web version.
Viewing post in CLIMB(Early Access) jam comments
Web versions are definitely important for taking part in jams. Many people won't play download only. We tend not to do them either, but will for our jam. Still, we run them through anti-virus scanners and will play in a VM or sandbox. We are also on Linux, so any Windows only games go through Wine or a VM.
For the web export it is nice to add a closing screen, since the game stays up in the browser showing the last screen. We just added a basic "Thank you for playing" scene, and load that above anything else just before exiting. That gives clear feedback to the player that the game reacted and has ended.
