There’s no way to start this feedback without first praising the art, because it’s simply wonderful! Seriously, amazing work on that. I really loved the overall aesthetic and the harmony you managed to create here. Nothing in the game feels out of place or like it belongs to “another world” — quite the opposite, everything feels integrated. Even the biomes, which are clearly very different from each other, still manage to feel visually cohesive.
The sense of progression at the beginning is very interesting and effective, enough to keep the player engaged right from the start. However, unfortunately, the game becomes a bit repetitive after some time due to the limited variety of enemies. That said, I don’t necessarily see this as a bad thing, considering how short the jam timeframe is, and honestly, I think you managed to accomplish a lot within such a limited amount of time.
During the gameplay, I didn’t encounter any bugs that prevented me from progressing, but two strange things happened with the UI. First, in the menu, whenever I clicked an option, I would instantly be taken to the new screen and only afterward the transition effect would play, which created a slightly odd feeling because of the delay. The second visual bug was related to the back button in the upgrade window, which somehow ended up in the top-left corner of my monitor haha. I’m not sure what happened there, but it almost made me close and reopen the game.
Overall, it’s a really great game, and I believe the two issues I experienced were probably related to my monitor or maybe even the web version itself, since browser versions often end up having some bizarre bugs from another dimension haha. Great game overall — it was very fun and interesting. Congratulations on the project, and I wish you the best of luck in the jam!
