Нello!
I liked that there is a large selection of improvements that I can buy. Also nicely done dialogues, it's cool that they are there and explain the plot. It's great that the progress is saved even after I refresh the page, it's sooo nice because I wouldn't want to lose all the levels I've passed.
I wish I could also attack with the mouse keys, not just J. Also regarding the shopping store, if you hold the cursor on the button with the price, the button makes the same sound forever. It scared me a little at first haha, this sound is very unpleasantly looping, if it happened by chance and it wasn't intended that way, I would be very happy to make just one short audio clip when hovering over the button, without looping.
Also, as far as I understand, when I go from the game to the menu or from the menu to the continue tab - the background melody restarts. At some point I wanted to go back to the menu because I forgot how it looks, then I went back to the game and pressed buttons fast enough to create a cacophony from those first few seconds of the background music. It would be nice if the music started at the beginning of the game and continued regardless of whether I was in the menu or in the game, maybe it would be cool to make a separate sound source and just control its volume (when you press the mute button, turn the volume to 0)
At level 4 something happened and the game was sooooo Of course, on the plus side - since the game was in slow motion, I was able to see all the details, the effects and the level)) I don't know what happened there, but both I and the enemy were lagging (I restarted the page but it was the same.
I liked that the last enemy was so strong and I couldn't get through it as easily as the previous ones. Then I went to farm money on the previous levels, hehe. And I noticed that for level 1 and 3 I can get +- the same amount of money (at level 2 I have a hard time with the enemy mechanics, so I didn't choose it for money farming, but this is my personal wish). I would like the levels to have a bigger difference in difficulty and, accordingly, in the reward
