Wow, you are so talented! Thanks a lot for the information of LMMS and I'll give it a try as well. Due to the interest for Hagrode and your other lovely games (I'll try all of them in my free time), I decide to join your Cosmic Horrors Jam of this year. Lacking experience in game jam, it might be a real challenge for me but I'll try my best.
Good luck with your jam!
