The games good but I've encountered a bug where the game won't let me progress after I upgraded any object to level 4 before I completed level 4

nearly beat it but then the repetitive dread kicked in.

really cool game i liked playing it for the first 7 levels but it could use some small tweeks.

im just going to throw some ideas out there:
>active effects would be cool like EMP to damage all sheilds
>active effect to launch a barrage of missiles like a heimindinger W from league
>ground and anti air missles could also be an active effect that stack so you can fire like 3 at once
>speed boost active effect
>different weapons to choose from, the general selection from defensive, hybrid, or offensive weapons

well it was a cool game but it kinda got boring right near the end.

It starts as a fun, average shooter. After a few levels though it can easily approach bullet hell which would be fine if your helicopter didn't move like a brick. Even with +25% maneuver it felt like i was dragging the helicopter around.

This is decent, but it's got potential to be great. For one, the chopper is so, so sluggish that it sort of kills the pace/tone of the game. Adding some kind of special attack with mouse click would be a positive and add more upgrades/variation. And this next thing is big... darkening the color of the enemy bullets and giving them some more impact so that I can really SEE THEM COMING IN would help a lot. Those little light-blue pellets and red dots are super easy to miss, which is frustrating. Also, different backdrops would give the game some variation, rather than flying past the same desert perpetually.
