Thanks for the feedback and testing out the game! I appreciate what you said about the game's polish, as usually I can barely get a game to a functioning state for these game jams. I feel like the wall jump controls definitely could've been implemented in a much friendlier way, there was even a stage during development where you didn't need to switch direction at all to wall jump, but I scrapped that for more "precise" controls (which was a huge mistake in hindsight).
You mentioned a zeroth loop. but I'm not entirely sure what that is. I'm assuming you're talking about starting the game off with less obstacles, but each loop there are more added, and if that is the case I entirely agree with you. I thought the pits were a cool idea, but that's coming from the perspective of someone who knows them off by heart, so I totally see where you're coming from there.
Once again, thanks for playing my game and giving some handy feedback :)
