I played you game! I really like the art style, clean and simple yet detailed enough so you understand where you are and usually where to go. The controls were intuitive and the jumping felt really good. I like the little squishy animation you have when you do jump, adds that little polish to the game. Overall, I really liked it! I didn't make it all the way through, there was a moving platform section I kept dying on and gave up after about 20 attempts haha I think you have a well put together game here. I LOVED the music a lot, it fit, it was interesting and it was just great! I really liked the natural progression of the game and the little "go this way" nudges you get from the green square and triangle that you are following/chasing. There were new features and challenges added in at the proper times and was easily digestible and removed a need for any tutorial. Great pacing.
There are only 3 things I would suggest you add in and they aren't anything game play related. I see that its a beta, so it's not complete yet so you may have these on your to-do lists, but thought I would give the feedback :)
1. Sound Effects - They are so powerful and beneficial, there were a few I noticed, but I think one for the player's jump, maybe the landing (on different surfaces possibly) and definitely the blue square pick ups.
2. Additional Animations/Effects - Mainly on the blue square pick ups, just a little spray of particles or they move up slightly and then dissolve or explode (nothing crazy, just a little 'pop') something like that to make picking them up "feel good", since you do it often.
3. Checkpoints - :) As I said above, I stopped after getting frustrated on the moving platform section. This section doesn't need to be altered, I need to be better haha but there was a middle platform between the two moving ones (right before jumping over the lasers on the moving platform) and that feels like a natural checkpoint. I had already done the first moving platform which was essentially just sitting on it. But after dying on the first or last laser on the second platform, I didn't want to keep going through the easy moving platform. I think that checkpoints (even just in a few spots) would be a nice addition.
Overall, great work! Looking forward to any updates. Couple questions:
Which engine do you use? I saw "Game maker" in the beginning, but not the normal logo they use, I use GMS2 myself.
Are you working by yourself or with a team?
