Isnt your bullet with the rotate towards angle thing enabled? Also, about the angle, do you have gravity?
I mean, the game im working is literally only about bullets and projectiles and i have yet 0 problems like you described.
About the general issues from the below post, yes. It is indeed a huge problem that we have some kind of rookie bugs (sound not working, "OR" event blocks buggy and etc) but what i feel is that we are kinda supported with the fixes "as soon as possible".
About the bugs itself, let me tell you this: I bought 7 months ago an expensive Dell notebook (5800 BRL, moreless 1900 USD) and about 4 days ago i lost my shit and it couldn't boot. Some general error about HDD and UEFI/boots options. I thought the HDD have died and ive lost everything damn thing i had on it. Opened, reconnect HDD and still nothing. Searching guidance on mobile i found a really old reddit post saying that this problem was some windows update and that it could be hotfixed with some knowledge and setup changes.
Anyway, i got the damn thing to boot and the update finished "flawless". My point is: if even Windows can't make a single stupid update bugfree, imagine Scirra/Construct/Ashley.
Also, i don't know if you are implying that im an Asheley evangelist or even one of his "fake accounts" but i just want to state that i am not.
About C being the only game language, eehhm... Yes and no., You have to be more open minded. Btw im no artist at all, im just some rookie with maybe 10~15 years of programming history, with computer science bachelor so i know a bit of what im talking about.
For the tool itself, i (and probably others) still think it has it niche. One example of work would be Healer's Quest that a fellow forum dude got on steam and by screens and video id say it is a good job, made by a guy whos probably solely a designer. IF he gets really into serious gaming dev, im pretty sure Unity/UE/Godot/Love/etc will be wayyyy easier to understand for him now.
To finish, im leaving this topic. I think the "path" it's taking leads to nowhere.
Edit: typos.
