Yo this one was surprisingly fun to play! It seems simplistic, but the challenge of the danger zones popping up all the time made it pretty entertaining!

Nice job.

Very cool idea! Like it

I haven't played something quite like this before, but it felt good. I beat about 20 bosses, but after upgrading my max ammo and ammo refill rate, I felt like the game didn't raise in difficulty to match the advantage I had. So the bosses began to feel easier and same-y. I think I noticed they were attacking more often though? Good concept. Good execution. Needs just a touch more variety in difficulty. Good job.

Awesome game concept with the changing instances mechanic. Quite difficult to get use to it, but when you do, it's satisfying

Wow, what a great use of truly minimal visuals. As the speed rams up it gets tough; I love it! There is even a shop, so you can try different combinations of upgrades, each time. Well done JJ, this is great!
