I agree with a few of the minor gripes in the other comments (mostly overly stick wall jumps) and the boss fight seemed to be bugged for me so unfortunately I couldn't see the ending (I could beat the first guy by stagger locking him but the the second one just went invincible and changing modes did nothing besides stop/starting the platform). 

Overall though this was fantastic, I loved the little touches like having a different aspect ratio on the 8-bit version, really increases the overall charm

This is really fun, I liked going for all the collectables

The pause screen was also great

Just a couple nit-picks:

jump height gets reduced when on downwards moving platforms which doesn't feel good

the staff recalls automatically when flying off screen so I sometimes accidently throw it right as it came back

I do my best to read all the comments on a game before commenting so I don’t say anything too redundant. Your game has had me reading the most of any I’ve played so far!

I love platformers. I’ve never played The Messenger and perhaps the controls are close to it, but I wasn’t a huge fan of how sticky the wall grabs felt. But that’s really the only platforming mechanic gripe I have. The movement feels great, and I love the small things like being able to jump higher/farther only if you’re holding the staff.

Graphics-wise, it’s already been said but the two styles are very nice. My only nitpick would be I wish there was some clearer visual indicator of which platforms/spikes would move when the mode was changed.

You guys already mentioned that the boss was one of the last things you were able to work on, I would’ve loved to have seen what you could have done with more time! I was confused while playing the boss on hard mode, it took me a long time to realize I needed to switch modes during the fight because the normal mode didn’t require that.

Hard mode was a nice challenge! Very much reminds me of Celeste B/C-sides. I think it was a great idea to take parts that might’ve felt difficult during playtesting and move them to their own dedicated level. Nice reward too ;)

Side note, I appreciate you guys not slapping an obnoxious fisheye CRT effect on the retro mode, it always hurts my head when I have to play games like that lol

Really great game that seems to be just the right length, and dificulty. Really hard to manage that in a jam, so fantastic job! Visually very appealing. I do think animations could maybe be improved, but understandable for the time constraint and two visual styles.

Very clean and very classic indeed! Feels very polished, controls smoothly and plays well. At first I also thought you had remastered a game, which I also get is what you're going for but also just confused me greatly at first, searching the internet to compare it to the original. Part of that is because while I like the remaster mode as a concept, it doesn't feel like the actual gameplay mirrors this. The graphics and music change to a lovingly crafted retro-look, but it makes less sense to me that the platforms would be in different places or would swap around, which for me feels like it has very little to do with remastering.

I'd have liked to see a deeper dive into the use of that theme, perhaps needing to use modern platformer convenient gameplay mechanics like coyote-time to overcome difficulties the 'original' version could not, or changing the way the character moves. Adore the music, also enjoy the idea of picking up concept art, fun to get some more insight into how it's made.

Also props on having settings and re-mappable keys at all!

Some small feedback notes (please view these in the context of having accomplished a great game!)

The original control scheme (S+Shift+Space)is uncomfortable for my hand, it doesn't feel quite natural with the S and Shift being so close. Pressing 5 times Shift on Windows is also a default shortcut for enabling sticky keys, which is unfortunate.

When using the staff for jumps near walls, sometimes the character would cling to the wall a little too easy.

The triple jump feels great when making horizontal distance, but due to having to hold it longer for higher jumps it doesn't feel as satisfying to use for making vertical distance, usually only reaching about 0.8 times higher than my original first jump using all 3 extra jumps.

Some even more minor things: The whole game is keyboard-controlled, but the menus are mouse controlled. The menu also immediately told me I had to switch to remastered mode to see the extras, but I hadn't even learned how - Perhaps this text could only be visible in the retro menu.

The 1controller2games and streaming menus were a bit lost on me. Many remastered games have this option, and it doesn't really feel like you're playing 2 games at the same time, but switching between them. This would have made more sense to me if both were visible at the same time taking the same inputs (which could be a mechanic all on its own!)

All in all a great entry to be proud of, congrats to everyone on the team!

I legitimately thought you cheated and just remastered one of your older games for the jam at first. Impressive work with this. Really like the flow of the mechanics. Well done

This is fantastic! Great creative use of theme, I really liked that the game actually needs you to switch between modes to solves puzzles. I ended up playing much longer than I planned to.
Initially the game froze up playing in browser but after that I only got minor hiccups when switching between modes.

Cute game! Loved the concept and the execution was really well done. Funny that the remastered version has impossible to complete areas that you need to revert to the old game to beat. I know that's the point of the game and mode but it's just funny to think about. haha Great job!
