First time Jam entry! Welcome. I agree a bit with some of the other comments. Your use of lighting was neat but the platforming is super hard. I'm not sure if the difficulty was intended. I wasn't able to get very far. One thing that I have to remind myself when making a game (even for a jam) is We play the game over and over, testing new features and fixing bugs. We tend to get really good at our games because we have that forced practice. Tuning in the difficulty can be really difficult. In a jam its good to go even a bit easier on the player because folks are trying to play a lot of the entries and don't always have a lot of time to master difficult games. 

Some unsolicited suggestions:

• Give the player a bit more time to master the controls in low stakes situations. Your single block platforms are tricky to land on and even stay on once you've landed. If you miss you fall down a long way and have to perform a bunch of jumps to get back to try again
• Coyote time will help the jumping feel more responsive. 
• It felt like your collision shape for the player was a pill. This made landing on those small boxes very hard. You could try some flatter shapes
• Sounds can help a lot to get the timing for things right. Landing and jumping right away, etc.

In any case good job on your first GWJ hope to see you next time!

Thanks for the game.

It took me a little bit of time to get used to the controls and the feeling of the jump as there were quite floaty (although I’m not really in to these types of games so that may be intended). I liked that every jump felt possible and it didn’t feel excessively difficult, though I didn’t get too far as I’m bad at it :D

I liked your character sprite and how the lighting changes his shirt on the way up. It definitely hits the theme being a classic jumping tower platformer.

I understand it's an Only Up style rage platformer but they aren't that conducive to game jams as they actively try to make the player quit instead of pushing on to see more of the game. The incredibly floaty platforming and almost immediately (just two levels up) tiny single square platforms make it very difficult to want to push onwards.

I'd also highly recommend jumping into one of the Godot 4.x releases so you can release a web build, wayyy more people are willing to play a web build than download an .exe.
