I was able to get 111 seconds. I think the gameplay works relatively well, the visuals and audio are pretty solid, and it has a cool name!
Game play more engaging/addictive. A few suggestions (in no particular order):
- Make it objective based. Give the player something to do other than survive.
- Make it round based, with upgrades in between each round.
- Include different "maps" rather than just a rectangle you could have different shapes or even mazes.
- Add a story mode.
- Include different enemy types.
- Include some collectible power ups (e.g., temporary invulnerability, speed boost, deflection, etc.)
- Allow the player to fight back in some way.
Visual feedback:
- Find a way to make the player character more thematic, the shapes are easy to understand, but don't make a lot of sense and aren't particularly engaging. Having different spaceships or aliens (or player unlockable/selectable skins) could help.
- Give some variety to the meteors.
Overall, I feel like you have a pretty promising foundation, and could see this turning into something really cool!
