Once I gave this sometime I actually enjoyed the concept quite a bit. I think it's a novel twist on the bullet hell genre, and I'm a sucker for single button/input style games. I'm playing on a mouse, specifically a Logitech G502 that I can "unlock" the screen wheel to be almost frictionless, which to me feels like the right meta for a game like this.

Couple constructive criticisms:

- Is there a pause button that I'm missing? If not, add one, I want to actually play this more but I need to be able to take breaks

- The beginning is too easy. I'm biased as I like difficult games that encourage mastery, but I found myself dying early on runs because I was getting impatient with how slow the early progression is

- I haven't played enough yet to know whether monsters eventually come from the top, but eventually they should, it would greatly increase the difficulty curve - Hitboxes feel a little meh, and don't seem to match the sprites

- If there's sound, it wasn't working for me, which leads to...

- Pump up the juice. You've got a great core loop, but you need the juice. One of my favorite game dev talks of all time would be perfect for you to watch and iterate with (https://www.youtube.com/watch?v=AJdEqssNZ-U)

- Monster diversity. Again, maybe I didn't play long enough yet to get to newer monsters, but from what I can tell the only diversity is their looks, health, and approach angle. Monsters that are faster and incentivize different movement, or that shoot back at you, or blow up after shooting so you have to avoid, etc.

I'll stop there, don't want an absolute laundry list. Keep at it, you've got a unique foundation, it'd be a shame not to polish it up!

Maybe add a charge meter that can fire a pulse weapon with a press of the spacebar after so many seconds of play. Unlock it later on in the game or something, idk.

I played for about 300 monsters and it got boring.

There’s a pause button on the bottom right. Or just tap P.
