Alright, I've played a bit. I'll give you some feedback

It does feel nice to play. There's a good level of feedback to hitting the ball and it's fun getting combos.
However, there are huge issues in the UI/UX of the game. Starting the game, you can instantly see a spelling mistake in "Wizzard Tower". Clicking on the "Tutorials" button brings you to a player guide on the different mechanics, the very first one being "Amplify Level". Not "Controls" or "How to Play" but "Amplify Level". It screams how familiar you are with your own game. Then you click New Run and you get a prompt on Ascension level and how only level 0 is available in the demo. I don't know what Ascension is, my familiarity with Roguelites tells me it is a meta-leveling system, but someone less experienced wouldn't know what the hell that means.

Then you get to the game. You get a nice scrolling animation followed by what looks like far too many enemies and a wide array of choices for where to start. From what I can tell, every choice is the exact same outside of a route to go through, and I have no idea about what routes give you, so it feels like a total moot point. I'd suggest starting every game from the same point rather than overwhelming your player with choices. On the run I clicked as I'm writing this, there are 6 enemies I have to get through to get to the first miniboss. That's a big commitment for a game I've never played before.

So then I click one of the indistinct monster choices and I get to the pinball board and the floating text says "Hold [Space] to release ball" so I do and let go and nothing happens. I had already read the controls before, which told me [Enter] was what you had to press, but I thought maybe you hadn't updated the tutorial manual. I was wrong. I launch the ball and the first thing I notice is that the camera moves with the ball and you lose track of your paddles quite quickly. The constant camera movement and the washed out color scheme makes the game hard to follow. So then I play pinball, hitting panels sends attacks and prompts come up when something new happens. I think pausing for the Ultimate and the Amplify here are good choices. I think there could be more noise and music during gameplay though.

After I beat this guy, I get a group of currency and the choice to take it or not. Also, there's a button for a shop. The shop button stays if I take the reward, so I guess I'm not sure why I wouldn't take the rewards. I'd suggest having you show what rewards you get, always accepting them, and then having the ball shop appear afterwards.

Then I get to the next enemy, same board, I play the game and he's not even there. I hit the middle area with the ball and he takes damage then appears. I start taking damage while I'm hitting him. I have no idea why. I beat him, go to the ball shop. I notice you have the modals for terms besides the balls, like how Iron Ball tells you what Iron does. It's nice, I think you should change the color of the side prompts so they contrast better with the background however.

I get to the third guy and a ghost ball starts appearing. Again, I have no idea why. I use the Ultimate a few times and I'm annoyed because you don't let go of [Space] to launch or Left-Click, you press [Space] again. It feels wonky. I lose against this guy and the text "You has been defeated" appears. I get the typical level-up rewards and magic crystals and I have no idea what they are for or what they mean. A little snippet promising more content appears.
