First of all, thank you for the feedback. This game is definitely not how I wanted it to be, as it was made amidst other work I was doing (and I did it ALL by myself). From the first to the second version, I thought about expanding the mechanics, enemies, and other things, but I only had a week and everything was left half-finished. The solution to deliver something within the jam deadline was to cut and simplify elements to make the game playable, even if not in the ideal way. There would be power-ups, a greater variety of enemies, and other things that I will implement in the future if I have time.
Regarding the character being a pacifist, no enemy explodes, they just go off-screen. As you can see in the first version, the stage enemies would be deactivated, but there is a bug in this programming that I couldn't fix in time, the solution was to make enemies simpler in every way, but they don't die, they are just deactivated and thrown off-screen. Finally, remember that this is a game jam game, which I made with the little free time I have, and that to make it a minimally viable product, I had to remove many things I wanted (like a map, for example). Even so, the game placed well in the two game jams I participated in, but I intend to make occasional updates and bring it closer to the version I originally conceived.
