Few comments

- Few more weapon choices would be nice

+ price seems OK, but I haven't finished the first stage yet.

+ Edges are fine by me

+ so are traps

+ Like the idea of unlimited lives, but you lose rooms

+ Love the RPG aspect, and I'd really really like to see this taken further in a shooter (perhaps Robokill 3?) - what about being able to personalise other aspects of your robot, as per a traditional RPG, so introduce some attributes like speed, defence, accuracy etc. This way, I could work towards building up a heavily armed but slow 'bot, or a fast accurate one that's fairly vulnerable.

Oh, if I buy it, does it include a Save function?

Also, I would love to know how many people buy the game, though I understand if you wouldn't want to disclose. Not that I would be able to duplicate this level of polish anyways.

My only complaint was that by the final few levels, my robot was so heavily armed that finishing was never in doubt - it was just a matter of time. That, and that the final boss "room" was pretty lame and short.

Great work-- looks good so far.
