Patterns were fun at the beginning, I enjoyed the puzzle-like nature of the levels, though they started getting pretty hard. Then I started using dash and I realized its absolutely broken and you can just mash space and pretty much not get hit at all due to iframes (I think the black bullets are an exception to this). Besides from that, I think the dash doesn't serve any integral purpose for the gameplay other than being a safety measure/difficulty reducer, so if you were to balance the levels I'd say you'd rather just remove the dash altogether. You can see how that other game in the jam, Tower of Bullets, uses dash as pretty much the central thing in the whole game, but here it's just there because the game is hard and it's helpful to overcome the difficulty (or in its current state, completely trivialize it if you spam it).
Some music and SFX would've been good too, even royalty-free music is fine, as long as it matches the game. SFX for turrets shooting (not overdone or else it will be a cacophony) and for the player's dash would work well too.
Also I think the door on the last level doesn't do anything, but you probably already knew that.

Responsive controls and a precise dash make the game a real blast to play. The difficulty is just right

Quite challenging, but very interesting and nice. I really like that you still managed to add a short in-game story to explain the game. You could though balance a bit more, especially with some enemy patterns (like from level 4 onwards) that seem a bit hard to comprehend. Good job anyway!

Pretty punishing but has an almost instant respawn so trying again is seamless. Fun game!

That is quite a challenging game you have there :) I like the difficulty progression with adding new turrets every now and then. Sound effects would be a nice bonus and bullets a hard to see sometimes.

I liked playing the game, it was challenging but for the first 5 levels it felt that the difficulty curve was just right. Afterwards it was challenging and I still in level 8 . I think that if you added audio it would make the game more lively, and maybe a little animation when the player is hit to indicate that would be good. generally I had fun playing it :)

The game is good, but without music and soundeffects it became a bit boring with time. The art style is good, controls are smooth and the dash mechanic is very usefull, but very op without a cooldown.

Controls are nice, as well as bullet hell theme :) what sells it short is the lack of sound or any game juice -kale

Spritework is real cute, controlls work well. Teh Collission appears very leanient and you can dodge between bullets. A bit to hard for me (but I suck at Bullet Hells!) - biggest gripe: No soundeffects, no BGM also no player Feedback when he dies. Those two things make the game feel a bit hollow and unfinished.

A game where you just dodge and don't fight back , interesting concept. The patterns are clear and with a bit of training it can be done. Challenging but also entertaining. Perhaps less levels but instead new mechanic(solve some puzzle, collect a key..) would have been better though. Dashing is a bit too strong. I could spam spacebar in most levels and just get through by luck. Overall good game :)

I like it! The concept of escaping the prison is really cool. The pattern are hard but fun to go through. It's just too bad for the sound but I'm sure you will figure it out! :)
