I’d like to say a few things I really enjoyed - first of all, the parallax effect in the background. It adds a great sense of depth to the scene, which is really really cool. I also like the color palette of the background, though I think it would be good to maintain consistency throughout the game. For example, it might help to adjust the font color in the menu to match it. Additionally, I believe that changing the font to something more stylized could be a small but impactful improvement.
As for the game mechanics, I noticed a few things that could improve the experience. When the player dies, all equipped gear is unequipped, and it needs to be re-equipped each time. It would be great if the gear progress was saved like with the in-game currency. I also wasn’t able to discover all the enemy types (there are at least three) but it would be helpful to see their HP or an indicator of how much more damage is needed to defeat them. Lastly, clicking on a piece of equipment instantly buys it without showing a description first. It would be nice to be able to read the description before buying.
Overall, I think the game has the potential to become a really fun and engaging experience if development continues! :)
