First of all, the game has good visual design. The environment is sparse, but the boss's appearance is great!
The combat feels nice, but it gets tiring over time. Because the environment is empty, there’s no reason or opportunity to maneuver. The boss just tanks your hits, so you end up just spam-clicking LMB.
The spin mechanic is very interesting, but it lacks depth. At the same time, there’s no point in thinking about where best to use it, yet you can also go through the entire boss fight without using it at all and not even realize it existed. Also, sometimes there’s simply no way to avoid taking damage in the game. Yes, this is compensated by the shield, but right now it feels like a game design crutch rather than a thoughtful solution to the problem.
It would be great if the boss had more varied attacks, as well as the ability to defend, and if the player had a more interesting environment and mechanics that encourage analyzing the situation.
Despite my criticism, I enjoyed the game. I can see the effort, and I really hope the developer makes more games like this and even better! I’d recommend expanding the visual style - it looks interesting against the modern backdrop.
And if you decide to develop this game further or make something similar, add other special spells. You’ll no longer be bound by the jam’s theme, and the idea of “jump in a certain way” to trigger a special spell is really cool!
