It was running really slow (on linux at least) and input was unresponsive (no idea why).
I like the touch of difficulty settings and the consideration of different keyboard layouts, I'm not a fan of forced fullscreen, though.

Thanks for the feedback! The game was developed & tested on Gentoo and I had no issues; one thing to note is that my code is... not exactly as optimized as it could be, and if you're playing with low CPU specs it might not run that well. If you could let me know what distro you're using and what your specs are, I'll do my best to help
I'm not sure how to fix your lag issue, but I can upload a windowed mode executable to fix the fullscreen issues. I'd just program in an F11 shortcut but the game was only made for a jam, so if I were to continue updates for it I'd probably just do the whole thing from scratch to be honest. Thanks again for the feedback!
