This is better than most do with shootorail, I'll give you that. I liked how the difficulty scaled up over time. You may want to check out your attack code though, the game seems to slow down significantly when you get the rapid fire power up. If you added levels, new weapons, etc this could turn out quite well. you've got a good start, but it's not a stopping point.
Slow isn't very beneficial when you consider that everything only hit single targets. On top of that, with how many defense type games there are, there needs to be more effects and upgrades and the like to be a really solid game.
4/5, with a little bit of work, this could be amazing. The graphics, sound, and game play are all nice, but you need to fix some grammatical errors ans some awkward wordings. It could also benefit from a few more options and some balance tweaking.
3/5 the graphics and sound are great. The game play itself could use a good bit of tweaking still, though. Exponential upgrades makes you pretty much immortal. On top of that, the game gets a bit repetitive without different foes.
My main issue with the game is that it isn't balanced well enough. The game starts out easy, then it gets pretty brutal, then it gets trivial again. I played as a vagrant, and by the time I got the -1 ap for attacks talent, the game was a joke. I just grabbed a 3 ap weapon and slaughtered everything. It is still that way at level 25.
I really get sick of seeing people down vote a game because they're not good at it. Stage 20 is EASILY doable. You can grab it with the chain and pull it over, for one. As for how hard it is to get a perfect on 19, cry me a river. It took me all of 5 tries to get a perfect on 19. That's your lack of skill and not even close to a good reason to knock 3 stars off of the rating.
I gotta rate this low because of the frustration factor. It's not that that game is too difficult, it is that the game requires far too much precision. It also adds to the annoyance when you're tweaking a design and it keeps offering you a solution. Some levels, even though I knew how to solve it, took me 15 minutes to get the rotation just right to win. I finally broke down and looked at a solution, and it was the same thing I was doing.
If you want, I could actually go through it and correct all of the English and whisper it to you so you could fix it. There is quite a bit wrong, but I'm a fairly good proofreader and wouldn't mind it too much.
Improve the music or add a mute button. The music got to me after 3 stages, and i had to quit playing even though I enjoy games like this. The music just got way too annoying to keep going.
It's a solid start. The men that show up starting on stage 12 are a bit too brutal though. Having to start all over makes the game less appealing. Additionally, some form of music would make the game far better.
Another thing I've noticed is the balance issues. For example, I managed to one hit kill the last boss. If you keep your dexterity and strength roughly even, you do so much damage you one hit everything and need no other stats. What this game needs most are bug fixes and balance testing first.
Other gripes with the game, and this is trying to be constructive criticism, not insults, include having no idea what the stats do. I've yet to see a miss or dodge, what does dexterity do? I'm also unsure what agility does and don't want to get that stat if it can't compete. Also, difficulty settings bothered me. I'm fine with harder difficulty making you take more damage or deal less, but all it does is reduce your experience gained making the game feel far more grindy on hard difficulty.
The game seems to often suffer from a lack of solid direction. For example, I'm having a hard time finding the demon they want me to slay. It also would be nice if it warned you that green land was far more powerful than the adjoined area.
I like the game as a rough thing, but the legendary items are FAR too luck based. I'm at 181 chests found without finding the legendary armor. It's quite annoying that raw luck is what is keeping me from the last achievement, and with how long I've played, I'd say those odds border on poor design.
I'm going to have to agree with quite a few other people, this amberial is not even as close to as good as the other stages. Some stages like Run! seemed to be infurating games of chance rather than a game of skill as the playform would regularly land standing up on its side at the bottom of the ramp or take off far too fast. Even when it looks like you did the same thing, the results varied.
