You mentioned that this was your first game jam, so congratulations on that!
I do have some criticisms for the game:
- First, the music. Unfortunately, it could be better. I can tell that there was an effort to make an interesting song, but there's room for improvement.
- The signpost graphic in the game looks off, maybe there was some issue with the way it was imported?
- The obstacles seem to be randomly placed, which is fun, but sometimes they get placed in a way that makes it impossible to beat the level.
- It can be unclear what can and can't hurt you. Coins seem to hurt you, while the purple platforms do not.
- The Lives counter seems sort of broken; it looks like every frame in which you're touching an obstacle, it takes a life away. If it's meant to give you three chances to hit something, try adding a countdown timer every time you get hit, and you can't lose health again until the timer is up.
- The volume slider doesn't work. It's fine to have unfinished parts in a jam game, though.
But I have some good things to say too:
- First of all, you finished a jam game. That's a pretty good feat; lots of people don't end up finishing, or maybe even never try. Finishing any game is a productive and rewarding experience. Congratulations!
- The idea is interesting: a gravity-swapping infinite runner where you play as a signpost? Lol. Also calling it "Signpost Bill" is funny.
- There are some issues with it, but it's decently fun. I could see someone spending a while playing it, and that's important.
Overall it's a very good job for your first jam, and I hope to see you make more games!
