This game has a cohesive pixel artstyle, with music that matches the theme well. The map design definitely has a metroidvania feel to it. I appreciate that it runs in the browser.
Here is what I would improve:
- Prevent player from being softlocked in front of boss door
- Improve spawnpoint system, so that the player only has to defeat the boss once
- Damaging squiggles in the climbing section should be red, to contrast with the wall/floor tiles.
- Add a hacking/attacking animation
Overall, this is a pretty fun concept that shows promise!
