This is a fun adventure game. I think the graphics, although still charming, really do the game a disservice, and I think it's actually a really fun and enjoyable game. I like the two-part puzzles you need to solve. It's quite easy but still a nice system. I especially like the later levels that you need to constantly switch between the two robots. It's super tense but very satisfying to pull off. The ending is also funny as heck, and I really had some giggles.
For some criticisms, I think the level puzzle felt a bit out of place, and since you don't know which one is working and which one isn't, it's just blindly pulling the levels, and something will eventually happen. That doesn't fell good for a puzzle game. The red cross on the enemies are also quite small and hard to press (or maybe I am playing via Snail Race's small broswer), which is a bit annoying for one of the battles.
Anyway, this is quite a hidden gem of a game. Well done!
