Nice wave shooter! The beginning was a bit slow with the “goldfish” enemies advancing slowly yet hard to it with the base weapon, but the tanks and upgrades made things more interesting as it went on. I didn’t catch that you could sell your sub-weapon to get another one at first. I suppose an upgraded sub-weapon can sell for a lot of money and therefore you would not lose your progression so far as you’d invest it elsewhere. It was fun playing with rate, damage and cooldown to find the best combination for the incoming waves.
Economy was a bit scarce, and having to choose between health recovery and permanent upgrade was a hard choice; I think that health pickups help reduce the difficulty, but I’m unusure if if they appear randomly or at regular intervals, so I couldn’t exactly integrate them in my calculations.
I played it on a laptop under Linux and performance was decent, at first I had issues with the camera but it turns out it only staggered when moving sideways (?)
I had one issue where a last enemy would remain, hidden on the platform. It was, in fact, a “fish” type enemy stuck between crates. Moving around would reveal it as it would move toward you.
A second issue, more annoying, was an armor heal pick-up that spawned right above a crate (because the enemy died there). I cannot jump so I could never get it. In fact, after game restart, it was still there, so I suspect pick-ups are not reset on restart! (could be exploited to start a new game which a bunch of health pick-ups in place, to use in case things go bad).
I would like to play more, but the beginning being a bit slow I’m a little less inclined to redo it just to test more sub-weapons and level-up configurations… I don’t know how many there are, but the lock-on was pretty useful against fish enemies, and the grenades more against tanks (it’s more a moving mine than a grenade launcher?). However, I found that sending a grenade against a wall is a good way to trigger an early explosion and kill fish you attracted previously all at once. Well, I did die after that, so not sure if the explosion as friendly-fire or if some fish just managed to hit me anyway…
