Really cool! Minimalistic (one button!) but engaging. And great execution - flawless. Only question was if difficulty increases gradually or suddenly (at least this is what I felt on around 35 seconds). But all in all - Well done. 

A lot of particle effects, just how I like it :) Very simple gameplay, but I enjoyed it. This idea definitely has potential to be expanded upon.

Criticism - Some of the sound effects are a bit too loud.  Gameplay-wise I think the meter fills up a little too fast, making it decently easy to survive if you get your timing right.  It would've been nicer to see a slower filling bar so you would have to make more quick time decisions.

Support - The art style is cute and simple, but it works.  The gameplay and relation to the theme are also very engaging and innovative.  The gameplay is also very intuitive and easy to grasp.

Just having one spell is such a cool take on the theme! The hits also felt very satisfying. Like, I really smashed those ghosts / masks with my magic.

Awesome work with this one. So simple yet I really enjoyed the game loop! The fact that it is one key also makes it perfect for mobile too. I can see this being expanded with different skins and ability upgrades to be a full fledged game. Awesome entry!!

Nice one key button game! good job

Hey,

Really simple and fun game loop here, a good polish of this game and a little more spell and enemy and this game will be really awesome.

Cheers!!!

Cool Concepts! nice simplification of the core gameplay loop, really adds a touch. innovative design too!. A little more polish and this game could be amazing for mobile.

I like what you did with simplifying the core gameplay loop! And while the sound effects are not exactly high fidelity, they are perfectly serviceable and add a ton of charm.
The game does start chugging past 30 seconds though. I am assuming that you're instantiating each enemy every time that they appear? If so, I'd recommend you look into object pooling to make the game run smoother. Brackeys has a good video on the topic here: 

31 seconds!

The sounds effect are hilarious.

cool game, i lasted 3 seconds the first playtrough, but then if you keep spawning the spell at the right time, you never die, (what i mean with this is that the spell area has a collider that gives you enough time to max out the charge again and again) .
