So many Kill the ___ titles these days, but what can you do when there's 3 thousand of them? I'll play it and give my words about it.
EDIT: Alright, time to tell people stuff.
Okay, so there's quite a few technical problems in this game (You can decide whether or not you want to fix them in later games.) There's restarting music, which you can fix by removing the sound_stop_all() lines in the playerKill script and the world object press R event, and finally in the playerKill script changing the sound_play(snd_Death) to sound_play(snd_onDeath) or something like that. Next, there's the weird window resizing when pressing R. Basically, what you want to do is go to the init room and change the view settings to what you want to be the normal view size (800*608 preferably.) That's basically it for technical problems, so now for a review.
Alright, so basically the game is needle as far as I went (I stopped on the water screen). There's a bit of variety of the tiles and you can tell that the maker was trying! The needle is also pretty generally good until the water screen. So here's some things you should work on. First, don't use deep blue water. Not only does it kind of make it hard to see in, but it also gives you singlejump in midair instead of double jump, which can be pretty hard on people when playing. Second, being able to shoot saves from far away isn't up my alley that much either, but depending on the game, it depends. Basically to make the saves system a little better in your games is to program a bullet blocker if you want one, or even make them S saves (press S while touching them to save). Lastly, be sure to test your games. Trust me, it helps. If you think your game is fun and people would like it, you're not wrong 99% of the time. For a first game, even though it had some problems, I could definitely see the effort put into it and I think that if you take some time to get settled into Gamemaker, you can make a really good game! I hope your next is better, and maybe try to fix on some of these problems (Especially the technical ones).
