Nice incremental game, always love to see these. I got 2 of every guy fully upgraded. It did miss something extra happening. Usually incremental games have a twist like a second currency, prestige, second mechanic on the side, and so on. But of course that's a lot of work for a jam game and I know that coming up with interesting mechanics for incremental games can be really tough. You got a great starting point for making a bigger incremental game if you would wish to do so.
I like that the bugs have different sprites for each tier, it's a lot of fun to see them evolve. The ladybug getting a really deep munching sound at the final tier, I loved that. Those sorts of touches really give the game character. The sound effects and music are very well done. The sprites and UI are nice and crisp.
All in all a great jam entry, keep it up! Very impressive overall especially for a solo game.
Note: I would recommend disabling fullscreen, since going fullscreen some time into the game made the browser window and entire browser hang for a long duration, after which the game crashed. And another time going out of fullscreen crashed it. This is in Firefox.
PS its also fun to see a jam entry made in Construct, I don't see Construct games too often.
