Played your game for a while (had to install the EXE, my browser crashed) and I like the action! Took me a moment to find the enemies and to learn how to lock the targets, but then it was quite fun to play.
Some feedback and questions:
- Is it possible to recharge your shield? There were small grey "thingies" dropped by killed enemies, but they were not collectable and my shield went weaker and weaker over time
- The second gun with the bigger circle made my viewport jump which was quite irritating, so I avoided using this weapon, your description says something about zooming on the enemy, but I found it kind of distracting
- The UI is a little small, there is so much space, I would go much bigger for e.g. the shield indicator
- The 3d graphics look good, especially your ship, also the particle effects / glow looks pretty good
- I am a little older, so I liked to play Desert Strike on my Sega back then, your game reminds me on that, might be a direction your game can go to (conquering certain areas with different kinds of threats)
Enjoyed playing your game. Keep it up!
