the game is painfully slow, and not in the sense that it's a tank game, in the sense there's an entire level full of red brick blocks that take a while for even the laser weapon to break and the health bars are so large taking out even the weakest enemies becomes a slog.
with max speed you still can barely strafe explosive attacks, without max visibility you need to go head first into danger to even see what is attacking you, without max turret speed aiming even becomes tedious, and good luck surviving without armour upgrades unless you invest in the weapons.
the tanks scale in health as the type increases, which in itself isn't a bad thing, until you realise explosive tanks make up most of the game, only changing in the final levels where they're along side laser tanks which are basically impossible to avoid (though at that point you'd have all base upgrades and other weapons so fair enough) which leads to the game spiking in difficulty as you're facing end game enemies early on turning battles into a grind with the base weapon but because they appear so early are made manageable with the basic turret destroying the challenge when you buy better weapons.
overall it's solid functionally but in terms of being fun, it's a time waster.
though the level editor is nice, though without codes it can only be used for self imposed challenge in a mode with infinite ammo and everything max upgraded.
