For any Mac user running into the "application can't be opened" error, download the itch.io app (https://itch.io/app), then download the game from there. That'll work without issue. Happy gaming!

I got it working, I'm doing my playthrough but i got stuck at the part where you get the ball launcher, i accidentally skippied the tutorial and cant figure out how to use the ability, also it unlocked this dash ability when I used K after getting the ball launcher which didnt feel right but it i lost that ability after reloading. How do I use the ball launcher? The polish is really great so far tho!
The dash ability is what you get for ripping the tip off of the ball launcher (though in hindsight I can see how that would be unintuitive as you're not launching objects, rather you're launching yourself). The ball launcher itself is not an ability you get. Also, you are correct that you lost the ability after reloading. Due to the short duration of the game, we opted not to include a save feature.
Glad you enjoyed so far!
