Had to run the game in python to find out what was happening, but I occasionally get an error that crashes the game.

Looks like that happens when you win the floating point math lottery by having the enemies bump the player or the phone table in exactly the wrong way.

The correct way to code it would be to check for zero here… but not doing that is faster which was important when I was making this game for a 48-hour jam.

Not planning on making any updates to the game at this point, but good catch, and I appreciate reporting the stack trace!

Hey thats pretty cool, are you working on any game as of right now ?

I love this game! It's so polished for a 48hrs game jam. Let me ask you a question, if you don't mind: was your experience with Pygbag good ? I've heard about performance drops but you game plays very smoothly... I'm about to join a game jam and I'd like to use Pygame since Python is the language I know more, but one of the requirements is that the game should be playable in the browser. I was leaning towards Js frameworks because of what I've heard about Pygbag but honestly from your game it doesn't seem that fps are an issue.

Thanks!...and most of all keep it up!

Thanks for playing!

Performance is a really big concern for pygbag, but if your game is simple it might not be too bad. I had to do a bunch of performance optimizations to get this to work (notice how the download has a vignette effect on it, but the web version doesn’t). The audio might be finicky as well.

Thanks for your reply! On Chrome I had a smooth experience even with sounds in your game. The only weird sound that I’ve heard was when restarting the game after game over, but that’s not a bi issue most of all considering that’s a game jam entry and not a full blown commercial game made in years of work. I honestly found the idea/game design was very effective: it’s fun even if it’s a small game! Big thumbs up!

As for the optimization required for Pygbag, I’m planning to do a small pixel art platformer, nothing with too many objects the thing is I’m not an expert programmer, I’ve already done a small game in the past but optimization wasn’t something I’ve taken care of, since I was actually struggling with finishing the game in its basic/unoptimized form. Do you have any suggestions for basic optimization or topics I should study to learn where to optimize? In the end I don’t have a clue of which elements can represent the bottlenecks…

Thanks!!!

Found a bug.
If you try to get an upgrade after the end of the game, it freezes.

Oof, thanks for playing and good find!

The game was created in two days, so I’m not at all surprised some bugs slipped through.
