Nice old school game, I love the auto-filter for items, missing that in many games. Also nice, that you don't have to care about mana with the cooldown base.
Nice game, but money atm quite useless if you are commando you just need Dual-wield SMG and you are fine. The Vengeance weapon you get at lvl 13 should have penetration laserbeam beam or splash damage, otherwise she is useless, to less ammo, even so she one hits every monster.
The possibility to find special items like High quality bullets is very nice. Not sure if Day 20-24 are bugged, you need to mass throw grenades or you get overrun without any chance to survive. After Day 25 the monster spawn rate gets rational again. For the weapon seller, make him a machine like in Death Space and rename money into resources or so, wich the machine needs to create the new weapons. But game has so far large potential to get very good. I played with chrome or chromium and had no problems so far ;)
Quiet nice little game, a little bit to easy on the first 13 level, after full reinforcements and mods for my main weapons I didn't really knew what to do with my money. Difficult was to get to know, who you keep boss from firing because he wrecks castle in 2-3 shots otherwise ^^
Hey I like the idea of a robot shopkeeper, I think I'll do that! :D
