Game works well on Wine 7.7

Well that was short, but fun ^^

The visuals looked neat and the music fit well.

You should consider displaying the controls  somewhere, even just on your itch page (it took me a little while to understand I had to use the mouse to shoot)

The collissions felt a bit weird some walls were solid others I could go through.

if you want to push the game a little further maybe try to make it possible to aim with your mouse. :)

Not much more to say. It's a game, it's finished & it's playable. so, well done :)

Fun and short, had a solid boss battle and made full use of the limitation and theme. It was a bit short, only 3 very quick levels, but still enjoyable!
I don't really get why I can only shoot to the right, and not in all directions though. Also the tiger boss would still hurt me even if I was nowhere near the left side of the room.

The graphics are solid. The controls are not documented and a bit weird, took me a while to find the "fire" button (it's the mouse button for people that wonder) which is strange with keyboard movement, unless you have mouse aiming as well.

The concept of starting with the boss and going backwards is good. But with only 3 levels, the execution leaves quite a bit to be desired.

Rest feels solid, no odd movement or collision bugs. Proper ending and in-between level transitions do make it feel more polished.
