Such a fun game, The CRT effect i think its a bit much, wish it was more suttle, but the game feels amazing, the audio visual feedback is satisfying, the gameplay is fun.
I would change the UI, if possible, to something more pleasant to look at, a bit more style to it.
Wish the tutorial was interactive, I took a while to "get it", but once the game starts you can grasp it pretty quick.
The Upgrades did not make much sense to me, took too long to get the progress bar to fill and the upgrades where mediocre, so i kind of just picked one at random.
Feels like this could go into a game with some meta progression and much more!
