Played through them both, although I am curious why you submitted two very similar games to the jam. They seem like could have been combined into one game. I'm leaving my feedback here instead of in reviews so I can talk about both.
Deep Coma:
I liked the art and music, as well as the platforming mechanics. The tutorial section was really slick. As for negative things, the gameplay was not unique and the game was pretty short. Short isn't too hard to fix. Gameplay not being unique is much harder to fix, but that's the downside of platformers.
DISC ROOM:
As in Deep Coma, the art and sound is really good, as well as the platforming. I did run into some issues in this game though. In the room that introduces the dash ability, if you die the falling platform does not respawn. I had to close the game and restart it to get past it. Upon re-reading the game page, I learned F5 would have worked as well, but neither is a good solution. Next, in the room with the disc cannon and the two buttons, I died right as I hit the second button and crashed the game.
ERROR in action number 1 of Create Event for object oDoor_3: Unable to find any instance for object index '26' name 'oPlayer_1' at gml_Object_oDoor_3_Create_0
Other than that, I don't have much to say about it that I didn't mention in Deep Coma.
Nice work on them. If you want to keep working, what they need most is content.
