I had some trouble understanding that I had to open the menu to upgrade at first, but once I got that it was pretty fun! I really like the upgrade system. The monochrome style looks pretty cool, and the audio is fitting. Feels very polished. Good job!

The stars effect looked really nice as it fades out -was pretty fun and i liked the music too!  Good job! :D

Visuals and audio are really good. Upgrade system is well thought out, I really liked how difficulty impacted pace of acquiring new upgrades. Utterly enjoyed playing. Great job!

Quite a cool combination of RPG level up elements with the shmup gameplay and having control over the difficulty increase was a nice touch. Nice job!

Manually controlling the difficulty to change the pacing of the game is an interesting idea.

Good job with the game.

the game is pretty neat but the difficulty going up is just feel to slow making it pretty boring and not fun at first. but everything is pretty nice is there any enemy variation cuz just one feel pretty boring or there is i just dont play long enough to see another one. 

This is actually pretty good, it almost feels like a clicker game where you just keep becoming more powerful over time. The particle effects and audio are also super juicy too.

I'd like to see more strategy though.

Cool game at first I didn't check the menu so I was thinking it was pretty boring wondering when it was going to go to the next level then say the stuff in the menu and it was a lot of fun only thing is you can abuse the git rid of 80% to continue because it allows you to even with zero so you can just spam the level up and go right to the boss, overall though good job.

Loved your Game :D I switched it to max difficulty to see what would happen and I wasn't disappointed :D The explosions are amazing, the music is super chill and I love the elegance of the simplicity of the game. And the revive mechanic feels really great ^^
