Idea is cool. I came to check this project out because I know one of the guys working on this btw
Music is a bit weird it doesnt really fit the 8-bit style but its pretty good (personal opinion)
I have the same issue with Fable Dev not knowing if I'm progressing the game or not, UI and indicators can use some work
The only issue I have with gameplay is the spinning blade thing (the one where you have to slip through the cracks to get by), the difficulty of that is way too hard, mainly because sometimes it'll spawn two and leaving no room for the player to get into the cracks in time.
The falling blades are cool that one I got no issues with.
Fireballs are a bit too easy but thats personal opinion
great game, just needs a lot of polishing, good luck with the game jam!
