Great vibes, love the music and retro crt shader. Initially i thought the paddle moves a bit sluggish, but then i got an upgrade for this, so it is intended. The progression system is nice and even though the base gameplay loop is quite simple, it is very fun and captivating.
One thing i disliked is that enemy paddles always move perfectly and just are too slow to catch balls at higher angles. I also encountered the shifted text bug on the web version and with it i could not continue past one of the shops.
Overall it's awesome work for such a short time, especially considering that you did all the gameplay, art and music yourself!
