Game looks good and sounds good. The gameplay on the human side is simple and fun. The raybot creation, on the other hand, could use a little work. At its core, it's definitely fun, and the aesthetic creation is great. I would've liked to have seen maybe a few more weapons for the robot to choose from, but it's no big deal. I think maybe being able to draw your own weapons instead of choosing from two or three different skins and maybe adding one or two more base weapons would work really well. My main issue is with the pattern programming. I think having to have players manually record the pattern themselves makes it a bit difficult to be able to actually do precisely what you want it to do. I often find myself repeating it over and over just to be able to get it right. Maybe in a future installment (or update?), it could be possible to do some simple AI programming to program the bosses (think Wario DIY) in addition to being able to manually record the boss. It's not TOTALLY necessary, but it would definitely alleviate some frustration with programming the pattern. What REALLY frustrates me, though, is this one bug that seems to have been mentioned in the author's comments and supposedly fixed. After lord knows how many tries, I FINALLY nail the pattern I want and try to open the exit to close the loop...but sometimes it won't open. I'm not sure what causes this, but after pattern testing for a certain amount of time, I am unable to open up the exit to finish the loop. Furthermore, whenever this bug DOES occur, ANOTHER bug occurs where trying to play as the human instead causes the game to bug out (doesn't spawn the level, game is basically unplayable until you quit the fight), and the only way to fix both of these is to reset the game. It's annoying enough to make me want to stop playing whenever it happens.
Simple, fun gameplay on human side
Fun to test out people's creations
Raybot creation is simple and intuitive and also fun.
Raybot weaponry could use a bit more aesthetic customization, and maybe even a few more base weapons
Having to manually record the boss patterns can be a hassle if you want precision
Nasty bug that basically makes it impossible to play the game
Overall, a pretty fun game that, with a few improvements, could really be awesome and live for quite a while.
