This is a really fun game concept! I love games that use ragdoll physics because they always surprise us with the unpredictable situations that can happen during gameplay—and your game definitely delivers on that.
I think the difficulty curve increases too abruptly. Even for a short game with just three levels, I believe it could be smoothed out a bit to help players feel more prepared for the next challenge.
The way you designed each level is great! You really have to think carefully about when and how to use each element. It’s a slightly complex process, but not impossible, making the game engaging while still being challenging.
A simple but effective improvement for the level selection menu would be to add a more contrasting color when hovering over an option. This would make it clearer when a player is about to select a level and take an action (in this case, choosing which stage to play).
Since the music is simple and doesn’t have much variation, it wouldn’t be a problem if it played continuously—especially considering how short the game is. Restarting the music at every level might create a slightly strange sensation, and some players who are sensitive to repetitive sounds might find it a bit off-putting. (This didn’t bother me personally, but it’s just a suggestion for future games or even for this one if you plan to expand it.)
The theme is interesting, but it could be even more noticeable in the gameplay. For example, instead of controlling the character directly, the player could be placing obstacles to prevent its death while it moves along a predetermined path. This might sound similar to the current design, but having the character constantly moving forward would enhance the feeling of being stuck in a loop, with the player’s goal being to "break" that cycle of death. Maybe this is a crazy idea, but I hope it makes sense to you too! Haha.
I really enjoyed the sound effect when the character dies—I have to admit, I found the scream pretty funny! One thing I noticed (and I hope it’s intentional, not a bug) is that there’s no blood, which keeps the game lighthearted and fun. If that was your goal, great job!
Overall, it’s a really fun game with solid physics. Congrats on the project, and I wish you the best of luck in the jam!
