Thank you for responding and getting back to me, and I'm sorry for taking a little bit to respond. But I tried running it in 3.5, and sadly, it didn't seem to work. I can often run other projects into later version without issues, so I don't believe the version has anything to do with it in this instance, but I may be wrong. Either way, thank you. But I believe it's due to the amount of resources loaded in the first scene, as long as it isn't a bother, do you think you could try optimization. again, I may be wrong. but thank you deeply from the bottom of my heart for taking the time to help, and even making this game, and giving back to the community. if you'd like to try updating the source code to a newer version before trying optimization, I understand. I'm not wanting you to waste time or anything, as time is important. thank you again, for helping me. But I'll be sure to check out your other games, thank you for recommending them. I can't wait to see what else you'll do.
Next update (0.4.1) is going to include a bunch of new areas, 2 mechanics and optimisations, when I finish it ill upload the source code again.
if you want it sooner, you could add me in discord so I send you a copy of the project with a different main scene, so you can actually load the project first (JoacoN#7161).
