Actually got it to work with enough fiddling around. First of all the name caused some issues. And after that:
After which the app started up just fine. Did not contain windows version by the way even though you have it marked as such. And yeah, you are missing some stuff from the web build too.
The game itself was quite fine. The difficulty was completely lopsided, the first inside section was the most difficult (and only difficult part). After that everything was a breeze. The spike hitboxes felt very unfair. Probably the same goes for the saws. Having the actual colliders of such items be much smaller than the actual visible item often makes it feel much better and more fair even though it would be kinda obviously favouring the player. That way there is never a bad feeling left to player about them not actually hitting the 1HKO on close calls.
The look was quite clean and nice, the parallax effect in the end there was somehow off. It was kinda nauseating looking but dunno why really. Did it move the wrong way or something? Adding in some sound effects would have given a lot.
Wall jumping didn't feel too good. Especially jumping off the wall then was awkward. Seems more like a by-product of not too well configured/coded platformer controls. I think you're just adding force on moving and then the friction kicks in near walls and boom you have an annoyingly sticky wall jump. Kinda easy to fix though. Start off with no friction on the player object. Then on contact with a wall and if still holding that direction, punch in some friction. Slowly reduce the friction so the wall hang will not grip forever and will slowly start to slip and drop. Then if jumping from such position, clear the friction again and direct the jump towards up and away from the wall. I think that would result in more of a classic wall jump with a better feel and more control.
Anyways, good job on your first game and jam entry! 👍 Hope you can get the web build issue ironed out so more people can actually play it.
