Thanks for playing!
I am very glad you enjoyed the existing level design, and puzzles in the world.
In regards to suggestions.
I was really debating implementation of the map, but in the end the priority went elsewhere, and I didn't manage to implement it on time.
I think I can see what you mean about the speed, but it kind of felt just right for me. I guess it may come down to personal preference, but then it is actually quite silly how slow the fireball is. I will give it some more thought for sure :D
With the obelisks I hoped that the player will recognize them, as they are present in the design of one of the slime enemies. However, I also agree, with their colours and general design they definitely appear to be very similar to the enviro sprites.
Lastly the health, thank you very much for the feedback about that. I was thinking about couple possible solutions to that issue, because I did notice that you can sometimes respawn with small amounts of health and no way to restore it. But then nobody really complained about it until now, and I wasn't sure if it was really an issue.
Again thank you very much for playing and giving all the suggestions! I will definitely consider them in the future.
