Hi again, hseiken!
I have looked into this issue, and sadly I have found no fix for it. As you mention, the system in question is lower end performance wise, and while the game is rather simple I think there are limitations to what will run things built with GameMaker Studio 2. The system requirements for the software (GMS2) itself is as follows (according to Google):
- 64bit Intel compatible Dual Core CPU.
- 2GB RAM.
- DX11 compliant graphics card.
- Microsoft Windows 7 (64bit only, Service Pack 1 or above)
- HDD with at least 3GB free disk space.
- Internet Connection.
How well this translates to the actual games made in GMS2 I do not know. I'll keep researching, and I'll definitely get back to you if I find a solution!
