I noticed a pretty nasty bug that makes the game completely unplayable on newer/gaming monitors.

At first I was completely and utterly pulling my hair out at the sheer difficulty. I mean, I have played Super Meat Boy, and yet I could not get past the third level of this game! I died over 100 times in level 3 alone, it felt like the game was just plain running too fast. The water just zooms up at the point where you pretty much have to speed-run the entire level, the green lizard character was hopping around with the speed of Sonic but with very little control, it barely would cling to wall for a quarter of a second before falling, it felt like I never had even close to enough time to react to anything, as if the entire game was running in fast forward....

.... and it turns out, that's exactly what was going on. I have a 144hz monitor, and I have seen this issue before with 2D games that have v-sync enabled. Many of them just simply advance the game by one frame every time the monitor refreshes, issue is, many also fail to take into account that there are monitors that operate at 120hz, 144hz, or even 240hz. Meaning the game can run anywhere from twice to FOUR times as fast on these monitors. And depending on the game, not all elements are even synced to the refresh, so it's possible for some elements of the game to run far faster than they are supposed to, but not others.

I have seen this exact issue crop up in other 2D games, I experienced it in Shovel Knight (was able to temporarily fix it by turning off V-Sync until the game was patched), Phantom Breaker (no option to disable V-Sync, so had to wait for a patch) and specific levels in Fox n Forest (no option to disable v-sync AND was not patched).

As soon as I used a setting to force my monitor into 60hz mode, this game became significantly more playable and felt like it was running in slow motion (likely because I was so used to it running so much faster). So this might be something you want to look into, more and more monitors are being manufactured with refresh rates of 120, 144, or 240hz nowadays, and this game is unplayable on all of those because of this.


Oh damn thanks for the notifying me. I actually have a TV with a higher refresh rate connected to my PC, so I tried the game on it and it seems to run just fine. I've also never heard similar reports from anyone else, so it might have to do with your PC? Either way, I'll make sure to add a V-Sync toggle key to this and all my future games though, just in case.

Not sure how it would work if you have a TV or multiple displays connected, it might not support outputting over 60Hz to a TV (since I think TVs only go above 60hz for active 3D, many of the ones that advertise that they are 120 or 240hz actually only accept a 60hz signal and internally up-convert it to 120 or 240) or it might lock all the displays to a refresh rate that all of them can do. 

 Glad to hear about the V-Sync toggle being added. While obviously fixing the issue would be preferred, I admit that is harder to do (especially if you don't have a similar display to test) and could be a lot of work depending on how much of the game is tied to the refresh. If getting it to work with v-sync is too much of an issue, is it possible to somehow have the game detect if the display is above 60hz and default the v-sync to off if it is?


I used GameMaker: Studio for this so unfortunately what I can do to fix the issue is very limited, but I'm still pretty sure that the issue isn't just with higher refresh rate monitors since several others played the games I made with the same engine before. I'm pretty sure that at least one of them would also have a higher refresh rate monitor.

I even found a forum thread someone asking if that would happen and everyone's answer seems to be no:


Actually nevermind I just got someone else saying the same thing, I guess I will have to look more into it LOL

Same situation for me on my 165 Hz monitor, only on the HTML 5 version. I made it to the 5th level  The downloaded version ran fine. Felt almost like slow-mo, so I beat it in 15 fails ;)


Oh. That makes sense. Now I feel better about making it to level 5 on my 165Hz monitor... I thought it was pretty punishing...
