Well, I'm afraid you've blown it, as many others have said. Unlike a lot of other people though I played through the whole first 10 waves, it pained me to do it but I tried what I can do. And then I fucking died on the last wave. Everyone has the same complaints, and I advice you fix them. No, I don't mean make a new and improved one next year, I mean as soon as you can. I wasn't keeping track of time but I must have been playing for roughly half an hour on the first level. That is WAY too long for a game where you get no upgrades, stay on the same layout and see the same four enemies all over again.
If you been playing the game for as long as I have you get used to it's controls, so those who complain about that are just impatient. However, the controls ARE really annoying, and they could have been better. Another thing that pissed me off is that you take damage when you fall. In a game about SURVIVING AGAINST WAVES OF ENEMIES. That feature does NOT belong in this type of game, even by itself it's a lame gimmick.
The number of enemies to kill may look small on paper, but for this, it just isn't. I have no idea what to say at this point but going through waves just takes way too fucking longer than necessary. You need to learn that there is a difference between adding challenge, and making the gameplay purposely shitty in attempt to gain that. You are not being any more "challenge" by removing an upgrade system, falling and taking damage, and adding extra momentum. In doing that, you have made a boring, repetitive game with nothing to compliment it's art style. The art is ok, and luckily I found no glitches, but do you think that's good enough to save it? The reason I died was do to some very, very bad luck, but in general, the game is too easy to even die! So I guess by your logic, the longer you make each and every wave, the "harder" you think it gets. This backfired on you, as you made the game so long, you made people hate. Congratulations.
For all of these bad complaints, I think I might know what the problem is. I looked on both of your medal scores and noticed that NEITHER of you have the medals for your own game. That explains a lot, it tells me that the two of you never tested it all the way through. Have you done so, instead of probably just moved and shot around to make sure everything worked fine, you immediately would have noticed that any one sane enough to get passed Wave 3 takes just way too god damn long to get anywhere. You should have tested the game yourself (or atleast hire someone to beta test it) and realized just how repetitive it was, if say you did test it 100%, your a lier. If you don't know how to add a shop/upgrade system: LEARN TO. If you didn't have enough time: FIX IT NOW. (Or at least make the upgrades permanent untill you get a new one for god sakes!)
The worst part? The amount these medals are worth are fucking shit. You shouldn't torture people if you give such a low reward.
Here's a list of some options, which I recommend that you do at least one if you know whats good for you.
1. Lower the amount of enemies towards the end.
2. Raise the medal scores.
3. Add something that would make people want to keep playing.
So to you, and to anyone else who adds medals onto their future projects, test your fucking games.
