Thank you so much for taking the time to play my game demo ShadowZael! I'm really happy to hear you enjoyed and clicked with it, I'm glad you noticed how it can be optimized for speedruns, that was a thing that naturally came from me play testing it hundreds of times and changing the rooms over and over to fit both styles of play! Amazed someone noticed that!
I 100% agree on the first room specially, I've spoken to a few people on this but if you check out my devlog you'll see progress where I change stuff up here: https://twitter.com/DerekBottles/status/1748110657864540253 (this is the new version of the first room, it wasn't difficult to change up but the safe zone/fall at the start was super important for people starting out!)
I'm also updating the tiles or rather adding more stuff to the aesthetic of that level, I want to strike a balance so it doesn't distract from the hazards in the room, specially like you mentioned the empty parts of some rooms but also looking very nice!
There's going to be a lot of positive changes and updates for the proper demo in a few months! Thank you for sticking around and I'll do my best to keep at it!
