Hey MacDudeDude and banado,
The Artstyle reminded me a bit of hyper light drifter mixed with the gameplay of undertale.
The gameloop is amazing and fun! The combat feels good and very polished, everything has small animations. The progression is nicely paced.
The UI is unfortunately not widescreen optimized and generally my only gripe about your game, the UI does not feel very intuitive. I lik ethe overall design of it, but when you hit TAB you're just visually overloaded. I like that you split up the Tabs on the right between Upgrade, Shop and Rod, but it took me a while to even see it as it didn't stick out.
The graphics are very good, the style feels mostly consistent and fitting to your game.
All in all a very good game! Good job :)
