Thanks for the comment.
I did not make it procedural generated this year. I think that is a bit overrated and hard to get right. So I think I will only go for that for games that need more variety and many playthroughs of same level, Which should only be a certain types of games.
I take your input on the speech into consideration. I do like how it turned out, and I have had comments about people that liked it. There were some other games in the jam that use voice acting with various results and I think it can work. The genre might be coming from the retro world, but far from all games in this category fits into the retro genre I think.
I've started to work on the post jam update and the collecting of minerals now fills up a bar that eventually unlocks the ability to find the crystals through the walls.
Thanks for playing!
