Hey, I'm not a Spanish speaker but here's some quick feedback that I'm typing as I play it:
- The opening text that shows up when you start the game ends too quickly. Even though I'm not a Spanish reader, assuming I was, there was barely enough time to read the final words before it cut off and moved on to the next part.
- Some hover effects over the menu buttons would be good I think. For example, if I hover over "Play" or "Controls" or "Quit", the word would highlight, showing me that I can click on it.
- BUG: If I click on the controls, then press the "Back" button multiple times very fast, the game crashes.
- The opening sequence is not skippable. Maybe escape for spacebar can skip it.
- I feel that at the start of the game, you might be throwing too many hazards at the player too fast. I think you should give them time to get used to the controls and the "rules" of the game. Right at the start you introduce 2 enemies, the spikes, and the sawblades all in one screen. They aren't hard to understand after dying to them a bunch, but I think you should avoid overwhelming the player so early.
- I think the background stands out a teeny bit too much, sometimes making it hard to see things like enemies and spikes. Maybe the background can be blurred, less saturated, or maybe not have black outlines to make "hide" it better.
- Some checkpoints would be nice. Dying and restarting all the way at the start is a bit frustrating.
Anyways, great work! I hope my feedback was helpful.
Also, I assume you want to know if your game is "fun", as in "enjoyable". Not "funny", as in "humourous" 😅
